UPDATE: The price is no longer $1,999 and there is now a new US distributor. This is still a very good piece even with the price bump, but the value proposition isn't as sweet as it was when this review went live. I still encourage an audition if possible.
you should try it with nos tubes they are much better than modern russian tubes. vintage mullards rca brimars or ge's are amazing ide start with mullards for smoothness ,brimars or rca's for warmth or ge's for clarity
I can say with confidence that you haven't heard what this amp can do until you swap the tube, it's a major difference. I've been trying to match my Totem Hawks with an amp for over a year with no luck and Sean advised me to give the Primo a try. I didn't love it until I changed the tube, now its a match made in heaven. For tubes, I tried a Mullard and a Golden Lion (both 12AT7), preferred the Golden Lion. Intrigued to try others but I'm happy for now.
Hey Dawid. Yeah, the price of these integrateds on the used market is awesome. I could even see people preferring the OG Unico, as the treble is more tame and the overall sound is slightly more romantic than what you get outta the Primo. I'm not sure if you still have it, but if ya do, enjoy!
@@ZeroFidelity Hey! Thanks for the reply. Yeah I still have it and really enjoy it. I prefer a more relaxed treble presentation, so it does work brilliantly for me. Great video by the way. 👍
I just bought a Parasound A23+ and a P6 preamp. I'm thrilled with the sound but had I seen or even known about this Unico Primo, I would have bought it for its simplicity alone.
No man you did the right thing buying Parasound products John Curl the designer did the right thing just because this thing is from Italy doesn't mean is exceptional I own Technics class AA amplifier with my C 19 Carver vacuum tube preamp and I love the sound
@@OscarSanchez-tk3hx No one here is saying that it is good because it is from Italia. But obiouvsly it is pretty good and more obiouvsly it comes from Italia.
Thanks for the video review and Shoutout Sean 😃 Glad the Golden Lion 12at7 helped smooth the sound out and gave the integrated better performace overall .
@@ZeroFidelity Thats great Sean , I had a feeling the lower gain and quality of the tube would make a difference , I have already spent a grand buying tube/valves I been rolling tubes like crazy both Power/Pre tubes , And one thing i have heard for the 'MOST' part is that one tube doesn't sound better than the other tube, its the Synergy pairing with Speaker/Front end. Example My Elac ub52s sound best with the Golden lions Imho. While my 🔺 40th Comete sound best with my Psvane classic tubes 😆 (quality does matter also) Hope that made since. But me loving the Doge 😆 Thanks again Sean for the shoutout think i done gained like 40 subscriber's 😃
Thanks @Zero Fidelity for the hint. @@tee-jaythestereo-bargainph2120 I loved a couple of videos I have watched from your channel. I'll stay tuned. Keep it up.
Zero I got some more pretubes on order may take about 2 weeks but would like you to try out the Psvane classic 12at7 actually 'seems' to have lower gain than the Golden lions 12at7 and much smoother but the lions have very good clarity ! Sean i am having so much fun tube rolling ! Can't wait to review the Doge but i was asked to wait until Sept 😥
Just caught Randy's review and saw you had reviewed this a while back. Seems like it would be a.good match with my Wharfedale Lintons. Thanks for the review.
Had the original Unico (with 2 tubes) for 6 or 7 years. Lovely amp! Upgraded to UR Unico 150 and it’s a beast of an amp. Will keep the original Unico for the second setup.
I owned that one, too... the original with the solid block wood remote with only volume up and down. I wish I hadn't sold that amp... It was gorgeous, and sounded beautiful.
Your review is just spot on. I had that. It is a good integrated. Good build. Good sound. Don’t stick finger into the plastic cover of the IR control. It will detach. 🤣😂
I am really happy with this amp. It really outshines a Vincent SV237 ($3k) Replacing the stock tube with a NOS RCA black plate 12AX7 ($100) did wonders, and also an excellent replacement tube is the PS Vane 12AX7 ($55)
@@wilsentwins The Vincent may be designed in Germany but as I recall made in China and the build quality of the Primo appears to be superior. The Primo is a powerful amp for it''s size. I have a 15x17 room and it drives my Dynaudio Special 40s and JBL 1600 HDI speakers to mid 80s db level at 3 to 4 out of 10 increments on the volume knob. The sound is round, nuanced, full, and tonally pleasing with lots of detail and "space". In comparison, the Vincent which I had for 30 days even after breaking, never matched the Primo for nuance, air and sound stage detail and scale. It was one of those products that just kind of presented the music with detail and good balance but it didn't "breathe" like the Primo. It sounded more solid-state while the Primo definitely gives you more tube flavor. With the Primo, changing the single tube has a marked impact on the sound. I have tested about eight different tubes in mine and it revealed each tubes character. (NOS RCA, PSVANE and Gold Lion Genelex being best in my opinion) Changing the tube in the Vincent seemed to yield little change. Vincent puts the tube up front in a little glass viewing space with a reflector behind it and a colored light. This arrangement make it difficult to get your fingers in there and change the tube. Seems like an audiophile version of a blue light on your back porch to attract flies. I also have a Schiit Freya+ and an Aegir amp. With a good cable these will run you $2000. Add a second Aegir and you are at $2800 all in with dual mono amps. This setup would be far superior to the Vincent for the same cost. In comparison, The Schiit setup is be a bit better than the Primo but they are very close and I listen to both. The Schiit setup also is three pieces and takes up more real estate. I never feel at all slighted listening to the Primo in comparison. I use a Bluesound streamer into a Schiit Gungnir DAC or an Audio Lab CRT transport for CDs.
@@fletchermunson6225 thanks for sharing all the details bro, appreciate it. I also keep an eye on schiit, i thought schiit was worse than vincent. in my country it is not easy to ab testing hifi.
@@wilsentwins This is just an opinion. I'd give a listen to the Vincent. It does offer lots of features and if you like it, well, who is to say what you will be satisfied with.
Cheers! Glad you mentioned Monitor Audio being a little tilted up in treble! Having enquired into Monitor Audio Silver 500's from a local dealer, he is totally anti Klipsch saying they are too bright, but to me: Monitor Audio is brighter than Klipsch. Go figure.
This Unico paired with a Mojo Dac goes to another level completely. This is my main rig for music listening and don't see any reason for upgrading for the value you get. I have the original version not the Primo. Rated at 85 Watts at 8 Ohm I can tell you I feel like I'm getting at least double that power. Only using about 30% when listening and it's plenty. It has the headroom for much more.
Exactly, I fully agree, I have the same well matched couple near 1.5 years. But now I replaced Mojo with Mojo 2! And now it is even better - imaging, instrument separation, depth, bass control. It is pretty fresh setup (2 weeks) but the differences are very obvious. And also I'm not going for anything else :)
@@tunio14ify Very nice and glad to hear that. What kind of speakers are you utilizing? I currently have Sonus Faber Venere 2.5 that I enjoy. They do well with a variety of music but shine with Classical , Jazz, some soft rock. Hard rock not so much.
The original Unico I had happened to match extremely well with the various speakers I had at the time: NHT 2.5i, Neat Mystique II, StudioLab Reference 1, NHT 1.3. It brought all of those speakers to new levels of performance in a big way. It, of course, didn't have the grunt and balls-to the-wall output that its predecessor, the Bryston 4bst, had. HOWEVER, to my ear, it was much more refined than the Bryston, and still played without strain and far louder than my normal listening levels. In that room, with any of those pairs of speakers, it was sonic bliss. I'd love to own another original.
Another great Zero Fidelity review.This is another amplifier I added to my Bucket List. And how do I get one of the big pimpin TEE JAY Stereo Bargainphile shirt ?
I have the Unison Primo SE model - 140 wpc @ 8 ohms matched with totem sttaf speakers. A very enjoyable match. Also checked the retail outlet Osage Audio Products, LLC and they feature the Primo at the same price-point.
This review was well done in my opinion. I love your review style and point of view. I’d love to hear that integrated for myself. Keep up the great work!
Thanks, Sean, for your description and encouragement of tube rolling. And with only one 12AX7 needed, it is especially easy to do. Preamp tubes like the 12 series definitely have an impact on sound due to their harmonic distortion signature, mostly 2nd order with some 3rd order, and little, of any,
I've got some killer 5751's that I'd love to hear in this unit. Paired with my Goldenear BRX I can imagine what the sonics overall would be like. Both are holo/spacial specialists, hang on baby.
@@stevensullivan5287 I have a GE 5751 in mine and it works wonders. The secret with this amp is to change the stock tube as soon as you can. It became such a better amp after the tube swap.
@@stevensullivan5287 tried a Gold Lion B759 yesterday. Wow, this is even better than the 5751. A little darker, more spacious presentation and deeper bass!
Simple designs usually means high quality sound to my ears. It brings to mind most of the Audible Illusions pre amps especially the Modulus line. Beautiful sound, simple design. The difference is that it is a tube preamp line.
Good to see this model is still being produced. Integrated amp without a DAC? Cool! I remember it being compared to my Musical Fidelity X-150v3 back in the naughties (04?). I had to dig the Mu-Fi out again when my Magnepan LRS arrived. It drives the 4ohm load well, thankfully. LRS need a high current amp: My 40w valve amp choked on the load! Sean:- Did you find a spec for 4ohm output from the Unico?
Dear Zero Fidelity, once I've heard the top of the line Unico 150 and it' really impress me for realism of reproduction, every instrument seems "real" and the voices had a beautiful organic texture. In the same session I've heard also the Luxman 507ux ii and the MF Nu Vista 600, the first very analitical but also musical, the second extremely smooth and round but both lacks something in terms of realism compared to the 150. Speakers was the Opera V SE from the same Unison Factory I think. It will be great if you could make a review on the 150, and maybe compare it to your favorite gear that stands behind you! :) Congrats for your chanel and reviews
Upon your glowing recommendation, I got this last week, and I love it! Your description is dead on. I also paired it with my Denafrips Ares II DAC and it's a match made in heaven. The imaging and layering are truly remarkable.
@@JPWinters KLH Concords which are like 94dB efficient, so the amp hits dynamic peaks over 100dB no problem. I normally listen at like 70-85dB average.I wouldn't know for 90dB average as it would hurt my ears too much.
I have had one since 2004, a delight. My very best hifi buy. My NHS hearing aides, had me in rapture, so much fades away, over time, that it becomes the norm. Its return shakes one.
Damn those Italians and their gorgeous workmanship. The Yamaha as1200 and kinky studios ex-m1 are totally different in terms of sound, but worthy competitors as well. So many good choices in the Under $3k price point
I was thinking how it would be great with my Denton 80th Anniversary, which is even more rolled off then those Lintons, or the Denton 85th Anniversary editions. But yea, it would be great with anything from that line, and probably the Diamond line too. Which I also love. Wharfedale speakers definitely don't get enough love IMHO. ✌️
@@fetaface1203 I got the Unico Primo It was a good match but I did not had Yamaha to compare with. Now I got the upgrade bug again and I am selling the Unico with the KLH.
@@jamescox4823 Honestly James. Having owned AVA products before, and not being very impressed at all. I seriously doubt that's anywhere near the SQ of this amp. I mean we're talking an actual tube preamp, with actual gain. Versus just adding more gain to an amp, and calling it a passive preamp. I'll take the two separate gain stages myself. All day, every day, and twice on Tuesdays. Thank you very much. Besides, it's a completely different sound signature anyway. Not to mention it's not made in Italy by a company that also makes $50,000 integrated tube amps. Sorry, but it's just on a lower rung. And while sure, many people will like it. How many will honestly like it better then the Unico? Besides Frank Van Alstine I mean. 🤣🤣🤣
@@amb3cog You are wrong, you need to listen to this amp. I have many amps including pure tube ultra valves and this one is categorically better. Do a little research, read all the reviews on this. My guess is you think B&W speakers sound good?
@@amb3cog So I call BS on your OPINION and the name calling starts! So now that we have established you are an opiniated snob we also know your political affiliation. Again I have several tube components and this amp is really good, esp paired with my Dennifrips DAC.
This is a great video. Very interesting hybrid amp. does anyone know how does this Unico Primo compare to the Heaven11 [Billy] hybrid amp in terms of sound stage ?
Great review, thanks. I have Unico Primo with Monitor Audio Silver 500 7G and I have a great sound for my taste. Now i’m serching that tube, but from technical specification from factory the original tube is ECC83 (12AX7) and not ECC81 (12AT7), how did you manage to use that valve?
I think it's beautiful. I love the looks of it. I just wished it had more power. I'm really looking to move up in the power department. It's ironic that you also show the M6si, as that has been my main choice, UNTIL, they started making the M6 500si again, which is what I really want. Great video. Thanks
Definitely need audition after seeing this, Bravo indeed! How would you rate if this is to pair with KLH model 5? Would it be too much of liveliness as compare to your favorite pairing using Yamaha AS1200?
Interesting. I had the original Unico (before Primo) with dual tubes in the preamp and absolutely loved it. I decided to switch to the Primo because it had a sub output and really regretted it. I really struggled with the harmonics in the high frequencies. Made all my music sound digital (even after rolling the tube). Especially evident on my Totem Rainmakers.
Thanks for sharing! I confess to purposefully omitting a fact from this review: I owned the original Unico. :D. I decided to say nothing as I know tons of people would expect me to recall an experience I had with a product from over 10 years ago as though it were yesterday. That said, what I do recall matches your experience. The original had a softer top-end and more of a romantic sound. It was extremely pleasant to the ears! Most of the time anyway. The problem was that the original homogenized the sound and wouldn't be happy with certain genres of music, like say, rock or electronic. The Primo seems more resolute and happy to play any form of music, with the tradeoff being that boost to the HF. I could see it not playing well with those Rainmakers or most speakers with metal domes.
@@ZeroFidelity Still have the original with two tubes. Was warmer, more organic, soulful and funky. As far as volume and Rock? I dare you to listen to the Allman's "At Fillmore East" through that amp. The Kevin gray rendition will knock you down with tone and color! And that's through a speaker rated at 86 sensitivity. Sound did remain warm at volume and sounded robust. Still running original military grade Phillips tubes!
Interesting review! How would this compare with, say, Marantz Model 30? I know there's no tone controls but I wonder how the phono stage compares for example? (Looking to upgrade from a Yamaha AS-801 here)
Hi mate greetings from Australia. Im going through the process of building up my 2 channel system, My first purchase was a Avid Sequel SP turntable with a SME Series 4 tonearm and 2M Bronze cart, phono stage is Simaudio MOON 110LP V2. Have just bought The Unico Primo which will replace a Sansui G-7700 powering a pair of AR94's which have been recently refurbished. I'm thinking of replacing the AR's with a pair of KLH Model 5's. In your opinion will these speakers add an improvement and will they pair well with my system. Cheers Enrico.
I bought a Unico Secondo used with an installed pair of RFT tubes...and I'm very happy with the sound... lush and satisfying os what I describe it.. Wondering how much different if I change it to a pair of Gold Lions.
Sean, there seems to have been a power supply upgrade on this model. The previous one has this curved heat sink around the transformer unlike the rectangular one in your sample. It also does not have that protective casing with Unison branding around the transformer. Some online stores talk about this and mention, how Unison improved the dynamics, bass performance with the upgrade which also included the caps. Do you have a view on this. I am seeing some 2nd hand options coming into the used market with the older PS. They pair with the RC2 remote. So I am assuming they are not the previous generation model pre 2011.

Hey Sean - great review and I appreciate the work your doing. I was wondering if you thought the Unico Primo with the tube roll would work well with my Klipsch RP8000F?
Can you define "loud volume" a little more? You say rock concert, but is that above 90db? Also, could you use the Tape Out to run to a headphone amp? This with the Sonus Faber Lumina II's?
Addressing your questions: 1) I can't define loud in DB for you, as quantifying that number will hinge on the speakers you use, the room you have them in, the distance you sit from your speakers, and what your ears consider to be loud. So to keep this simple, I'll say this: If you want to listen at volumes above 90dB with the Unico Primo and DON'T want your ears ripped off in the process, you'll need to use power sensitive speakers from the likes of say, Klipsch or Tekton. 2). I don't believe the TAPE OUT will work. You'd have to consult the manufacturer to verify for sure . Having said that, the low-impedance out (labeled 'sub') should work. 3). I'm guessing the Primo will sound good with the Luminas based off of what I've read about those speakers, but since I haven't heard the combo, I cannot say for sure.
Hey Sean great review. I have been considering the Primo lately and am wondering if you have heard the Billie Mk2 and if so, how would you compare it to the Primo?
Hello Sean, first time commenting on your review and I love it. I have a UR unico nuovo, an older model but the inside is pretty much the same layout. I noticed that you said you didn’t have the phono stage but if I’m correct, if you had the top of, directly behind the tube is a small print plate vertically mounted. In my layout that is where my phonostage is connected. So isn’t that the phono stage in your amp as well? Great review! I love my amp and if possible will se if I can update to the bigger brother. Thanks for all the details and the work in your video’s. Love it. Peace…
The assertion of the high end could be due to tube compression. The beautiful thing about tube’s non-linear response which is octave distortion. But frequency response effect occurs because larger amplitude sounds get more reduction, so highs are relatively louder. Do the compression at lower power, in the pre-amp, allows it to be done more precisely quadratic.
One more great review Sean !!! Hello from Greece :) You mention that the amp has elevated treble. My question is this: You always use a standard (external) DAC to review a unit ? Because if indeed true, this means we do not know exactly how fi the Primo performs since is effected by the sound of the dac. If not, you test with an analog source? And you also compare the Primo with the m6si. Which dac is used with the Primo? Just curious :) Cheers !
My Cambridge CXA81 is my first and only experience with a decent A/B amp..and previously I only used class D amps driving active speakers, like my Sonos era 300s/Arc or Adam A7X monitors. I’m curious about your point about the Primo not handling high dynamic range tracks well like a class D .. Is this typical of all A/B amps? Been listening to tracks with huge range on my CXA81+ Kef Q350s and it seems to handle dynamics as well as my class D gear (Cat Stephens: Tea for the Tillerman in particular has a lot of soft/quiet passages that suddenly shift to loads of energy) Maybe my ear isn’t well trained enough to pick up these differences or nuances yet.
Enjoyed the review. I have the unico due with two 12ax7 input tubes. Do you think it would be safe trying two 12at7 tubes? I have a pair of Siemens NOS 12at7 tubes on hand…
I'm still using the original Unico. Similar to this, but 2 ECC82 tubes. I rarely crank the volume, but the sound does change when I do. Some people say it gets 'airy', I think thin.
I had the Unico SE with Triangle Celius ES since the early 2000's. A bit of a mishap forced me to swap my Unico SE with its big brother the Unico Secondo a couple of years ago. And when Sean made the comparison between Triangle's Australe EZ with the Forte III's, I decided to pull the trigger on the Australe since no one around here carries Klipsch's Heritage speakers. Couldn't be happier. Now I'm thinking that maybe I should look into tube rolling. It's a toss-up between the Golden Lions & Telefunken Black Diamond, both around $125 / matched pair.
Jay - I'm wondering the same thing. I have been using the Vincent SV-500 for this past year and really enjoying it, but wondering if the Unico would be a nice upgrade!
@@jaysworld5378 I have noticed the same thing - no reviewers are discussing the Vincent amps. As someone who hasn't access to a local store and relies on the comments of reviewers, I would love to see Sean and some of the other primary reviewers take some time to compare the Vincent SV-500 to other amps they've spent time with. As you mentioned, is something like the Unico Primo a big improvement over the Vincent, or are we needing to spend well into the next pricing range (like Hegel) to get that big improvement.
Shawn. I think I want to try the Unison Research Primo or Due. Are we sure audio legacy is an authorized dealer for UR? Because I was on the UR site and they mention no authorized dealers in the USA. I wrote them directly so I hope to hear back from them, but if you know for sure please LMK.
Mark, I bought my Primo thru Audio Legacy but the real “Main Man” is named Boris (Filiated or Affiliated Electronics?) .. Hillsborough New Jersey.. He does all the mastery fixing if necessary and did tell me he’s the “Boss” & Owner but sells thru Audio Legacy.. Probably for tax purposes.. He has the Units here in the US & sells high-end power cables & other accessories.. If he runs out of amplifiers he orders more of whatever unit the customer wants , shipping them to his Audio Legacy on line store & usually gets it to you fast from there.. He’s very honest to deal with👍 If you call him (get his number thru Audio Legacy), to ask questions about his AL store tell him R. D.H in Florida sent you👍 You can also hear the Primo on my YT channel.. Hope this eases your mind.. And they have a return policy if you’re not happy, but I can tell you from personal experience, The Primo is Primo..
There is a substantial market in the USA for a) tube or tubey sound.b) lively presentation c) subwoofer output to compensate down low (and offload quite a lot of power handling to the powered sub, giving the amp more breathing room). Power? 80wpc is still enough, but not for a "party amp". How does it handle current capability and crazy speakers that go down to 2 Ohms (sometimes even less)? How is customer support? When you plonk 2000 down you have to bear this in mind.
HI, juste discovered your chanel and like it a lot even if you speak very quick some tims ^^ Could you compar it to the tsakidiris Aeolos ? That would be a very intresting comparaison for sure Thanks anyway
@Zero Fidelity Sir, would you mind giving your two cents on the Unison Research Unico Due Integrated Amplifier? I'm looking for a dual-mono or stereo amp to drive Focal Chora 826 tower speakers.
Good review, but not at all a revelation as Unicos have been rated highly by reviewers and users for years. If you need more grunt and db's then get the Unico Secondo. I have used one for 11years and absolutely love it. Tests at over 110w into 8 and 180w into 4 ohms. Has driven ATC, Kef Ref one-two and currently Canton A45 without breaking a sweat. Beautifully built with dynamic, balanced, detailed SQ. Cheers.
I have found your comparison with the M6si the most intriguing part of the video. Considering there are some similarities in their respective sound signatures with the higher registers being slightly elevated, would the speaker matching recommendation for M6si be similar as well: e.g. Buchardt Audio S400, Dynaudio Evoke Series, Harbeth, etc? Thanks and keep up the good work 👍
I had 3 integrated amps: Naim Supernait 3, M6si & Unico Primo (with the stock tube replaced by a GE 5751). Tried all 3 with my Harbeth M30.1. I sold the M6si as I found it had too much grit in the trebble and the soundstage was too forward. The Supernait 3 is now paired with my Martin Logan Montis in another system while the Primo is happy driving the Harbeths. This is one of the most underestimated integrated amps out there... if you replace the stock tube...
@@enjoyunreality That is a tough question. I think if you factor in price: yes. In absolute terms where price is not factored in, I think the Naim is more revealing and has more drive, especially with harder to drive speakers like my Martin Logan Montis. I now have a Gold Lion tube in the Primo and I think it makes sweeter with small jazz ensembles or vocal music. At more than 2X the price, you have to realy dedicated to go for the Naim instead of the Primo...
Erik. I have the Tekton Lore Reference speakers as well. I’m using a Musical Fidelity M2si integrated which I find slightly on the bright side. What amp do you use? Thanks!
Hi Sean!, Excellent review BTW. How would you say the Unico Primo compares to the Yamaha A-S2200 in high-frequencies performance and in overall sound. I am looking to buy an integrated amplifier and want something for upbeat tempo music such as rock/jazz fusion. I don't like smooth rolled-off highs.
UPDATE: The price is no longer $1,999 and there is now a new US distributor. This is still a very good piece even with the price bump, but the value proposition isn't as sweet as it was when this review went live. I still encourage an audition if possible.
Sean, could you precise precise plus the reference of the Gold Lion tube? i would like to change it.
you should try it with nos tubes they are much better than modern russian tubes. vintage mullards rca brimars or ge's are amazing ide start with mullards for smoothness ,brimars or rca's for warmth or ge's for clarity
@@yaniv-nos-tubes considering this amp, do you think I can get less wormth, (shift towards bright) from it than from cambridge cxa81?
I can say with confidence that you haven't heard what this amp can do until you swap the tube, it's a major difference. I've been trying to match my Totem Hawks with an amp for over a year with no luck and Sean advised me to give the Primo a try. I didn't love it until I changed the tube, now its a match made in heaven. For tubes, I tried a Mullard and a Golden Lion (both 12AT7), preferred the Golden Lion. Intrigued to try others but I'm happy for now.
Thanks for sharing. Currently running hawks with Hegel h160. Maybe will try primo unico someday
After much deliberation i went with the Unico Primo amp, plays very well with my old Italian speakers, looks stunningly understated, love the amp!
I like the distinction you make between a listener and an enjoyer.
Nice to see you doing a good-ole-fashion review again…this looks beautiful! Thanks
... that thing is absolutely fantastic - great review, and thx for exposing this amp to a greater audience!
I bought the OG version of this amp recently for $870 used. Great sounding amp and it comes with a solid wood remote which is a nice touch.
Wow, never knew you are also into Hi-fi stuff.
Hey Dawid. Yeah, the price of these integrateds on the used market is awesome. I could even see people preferring the OG Unico, as the treble is more tame and the overall sound is slightly more romantic than what you get outta the Primo. I'm not sure if you still have it, but if ya do, enjoy!
@@ZeroFidelity Hey! Thanks for the reply. Yeah I still have it and really enjoy it. I prefer a more relaxed treble presentation, so it does work brilliantly for me. Great video by the way. 👍

Yes like sugden stuff
Guarantee of quality.
BEAUTIFUL unit….as visually striking as my Italian espresso machine!! Molto Bella!
Thanks for increasing my awareness! 👍🏼
Glad you review Unico. It sounds really good.
I just bought a Parasound A23+ and a P6 preamp. I'm thrilled with the sound but had I seen or even known about this Unico Primo, I would have bought it for its simplicity alone.
No man you did the right thing buying Parasound products John Curl the designer did the right thing just because this thing is from Italy doesn't mean is exceptional I own Technics class AA amplifier with my C 19 Carver vacuum tube preamp and I love the sound
@@OscarSanchez-tk3hx No one here is saying that it is good because it is from Italia. But obiouvsly it is pretty good and more obiouvsly it comes from Italia.
Simplicity is the way to go. Always.
Great job Sean. If I didn’t already own a pretty satisfying system, this would be at the top of my list to audition
I fall in love with the Italian sound when I listened to a pair of Rosso Fiorentino at an audio show a few years back.
Thanks for the video review and Shoutout Sean 😃
Glad the Golden Lion 12at7 helped smooth the sound out and gave the integrated better performace overall .
Thank YOU man! I didn't expect the 12AT7 to do much, and while it doesn't radically change the sound, it did improve things for the better.
@@ZeroFidelity Thats great Sean , I had a feeling the lower gain and quality of the tube would make a difference ,
I have already spent a grand buying
tube/valves I been rolling tubes like crazy both Power/Pre tubes , And one thing i have heard for the 'MOST' part is that one tube doesn't sound better than the other tube, its the Synergy pairing with Speaker/Front end. Example
My Elac ub52s sound best with the Golden lions Imho. While my
🔺 40th Comete sound best with my Psvane classic tubes 😆

Sean i am having so much fun tube rolling ! Can't wait to review the Doge but i was asked to wait until Sept 😥
Hi,
Great review as always.
Totally agree. Unison Research shines in the 'entry' level amps!
Just caught Randy's review and saw you had reviewed this a while back. Seems like it would be a.good match with my Wharfedale Lintons. Thanks for the review.
Had the original Unico (with 2 tubes) for 6 or 7 years. Lovely amp! Upgraded to UR Unico 150 and it’s a beast of an amp. Will keep the original Unico for the second setup.
I owned that one, too... the original with the solid block wood remote with only volume up and down. I wish I hadn't sold that amp... It was gorgeous, and sounded beautiful.
Your review is just spot on. I had that. It is a good integrated. Good build. Good sound. Don’t stick finger into the plastic cover of the IR control. It will detach. 🤣😂
haha Thanks for the tip!
I am really happy with this amp. It really outshines a Vincent SV237 ($3k) Replacing the stock tube with a NOS RCA black plate 12AX7 ($100) did wonders, and also an excellent replacement tube is the PS Vane 12AX7 ($55)
Vincent SV 237 MK is on my list, is it bad compare to this unico primo? Can we the noob change the tube in the unico primo?
@@wilsentwins The Vincent may be designed in Germany but as I recall made in China and the build quality of the Primo appears to be superior. The Primo is a powerful amp for it''s size. I have a 15x17 room and it drives my Dynaudio Special 40s and JBL 1600 HDI speakers to mid 80s db level at 3 to 4 out of 10 increments on the volume knob. The sound is round, nuanced, full, and tonally pleasing with lots of detail and "space". In comparison, the Vincent which I had for 30 days even after breaking, never matched the Primo for nuance, air and sound stage detail and scale. It was one of those products that just kind of presented the music with detail and good balance but it didn't "breathe" like the Primo. It sounded more solid-state while the Primo definitely gives you more tube flavor. With the Primo, changing the single tube has a marked impact on the sound. I have tested about eight different tubes in mine and it revealed each tubes character. (NOS RCA, PSVANE and Gold Lion Genelex being best in my opinion) Changing the tube in the Vincent seemed to yield little change. Vincent puts the tube up front in a little glass viewing space with a reflector behind it and a colored light. This arrangement make it difficult to get your fingers in there and change the tube. Seems like an audiophile version of a blue light on your back porch to attract flies. I also have a Schiit Freya+ and an Aegir amp. With a good cable these will run you $2000. Add a second Aegir and you are at $2800 all in with dual mono amps. This setup would be far superior to the Vincent for the same cost. In comparison, The Schiit setup is be a bit better than the Primo but they are very close and I listen to both. The Schiit setup also is three pieces and takes up more real estate. I never feel at all slighted listening to the Primo in comparison. I use a Bluesound streamer into a Schiit Gungnir DAC or an Audio Lab CRT transport for CDs.
@@fletchermunson6225 thanks for sharing all the details bro, appreciate it. I also keep an eye on schiit, i thought schiit was worse than vincent. in my country it is not easy to ab testing hifi.
@@wilsentwins This is just an opinion. I'd give a listen to the Vincent. It does offer lots of features and if you like it, well, who is to say what you will be satisfied with.
@@fletchermunson6225 bro, I just read it again, are you saying we can use aegir + vidar together?
Great review as always! When one of my vintage systems bites the dust this will be a top contender to replace it. Thanks and Tee-Jay rocks.
Great, informative, and fun review! Thanks!
Best review on this unit that I have heard to date. Great job. Just subscribed to your channel.
Cheers! Glad you mentioned Monitor Audio being a little tilted up in treble! Having enquired into Monitor Audio Silver 500's from a local dealer, he is totally anti Klipsch saying they are too bright, but to me: Monitor Audio is brighter than Klipsch. Go figure.
Great review. Love the format & style.
This Unico paired with a Mojo Dac goes to another level completely. This is my main rig for music listening and don't see any reason for upgrading for the value you get. I have the original version not the Primo. Rated at 85 Watts at 8 Ohm I can tell you I feel like I'm getting at least double that power. Only using about 30% when listening and it's plenty. It has the headroom for much more.
Exactly, I fully agree, I have the same well matched couple near 1.5 years. But now I replaced Mojo with Mojo 2!
And now it is even better - imaging, instrument separation, depth, bass control. It is pretty fresh setup (2 weeks) but the differences are very obvious.
And also I'm not going for anything else :)
@@tunio14ify Very nice and glad to hear that. What kind of speakers are you utilizing?
I currently have Sonus Faber Venere 2.5 that I enjoy. They do well with a variety of music but shine with Classical , Jazz, some soft rock. Hard rock not so much.
Very cool Shawn. I have always enjoyed your class.
wonder how it would compare with my Rega Brio?
The original Unico I had happened to match extremely well with the various speakers I had at the time: NHT 2.5i, Neat Mystique II, StudioLab Reference 1, NHT 1.3. It brought all of those speakers to new levels of performance in a big way. It, of course, didn't have the grunt and balls-to the-wall output that its predecessor, the Bryston 4bst, had. HOWEVER, to my ear, it was much more refined than the Bryston, and still played without strain and far louder than my normal listening levels. In that room, with any of those pairs of speakers, it was sonic bliss. I'd love to own another original.
Another great Zero Fidelity review.This is another amplifier I added to my Bucket List. And how do I get one of the big pimpin TEE JAY Stereo Bargainphile shirt ?
I got ya , Thomas I will email you on me lunch break today , pulling those 12hr shifts shhhhweee !
I have the Unison Primo SE model - 140 wpc @ 8 ohms matched with totem sttaf speakers. A very enjoyable match. Also checked the retail outlet Osage Audio Products, LLC and they feature the Primo at the same price-point.
Would this be a good pairing with the ls50 metas and denafrips ares2 dac? Thanks.
This review was well done in my opinion. I love your review style and point of view. I’d love to hear that integrated for myself.
Keep up the great work!
Thanks, Sean, for your description and encouragement of tube rolling. And with only one 12AX7 needed, it is especially easy to do. Preamp tubes like the 12 series definitely have an impact on sound due to their harmonic distortion signature, mostly 2nd order with some 3rd order, and little, of any,
I've got some killer 5751's that I'd love to hear in this unit. Paired with my Goldenear BRX I can imagine what the sonics overall would be like. Both are holo/spacial specialists, hang on baby.
@@stevensullivan5287 I have a GE 5751 in mine and it works wonders. The secret with this amp is to change the stock tube as soon as you can. It became such a better amp after the tube swap.
@@danielblais5047 Thanks for the insight, was pretty sure it would make a difference.
@@stevensullivan5287 tried a Gold Lion B759 yesterday. Wow, this is even better than the 5751. A little darker, more spacious presentation and deeper bass!
Simple designs usually means high quality sound to my ears. It brings to mind most of the Audible Illusions pre amps especially the Modulus line. Beautiful sound, simple design. The difference is that it is a tube preamp line.
I saw another review of this unico primo has 2 tubes? Is this the old model?
How on earth you always review something that nobody else even heard of. Bravo 🙌👏🏻
PS 1st to comment finally😂
My favorite components usually come from the more obscure companies! Thanks for watching!
Oh no, last week it was an Australian accent and now it's Italian!
Wow....that's VERY well made. Far nicer inside than I expected. Italians.....who knew?😉
Good to see this model is still being produced. Integrated amp without a DAC? Cool!
I remember it being compared to my Musical Fidelity X-150v3 back in the naughties (04?). I had to dig the Mu-Fi out again when my Magnepan LRS arrived. It drives the 4ohm load well, thankfully. LRS need a high current amp: My 40w valve amp choked on the load!
Sean:- Did you find a spec for 4ohm output from the Unico?
Dear Zero Fidelity, once I've heard the top of the line Unico 150 and it' really impress me for realism of reproduction, every instrument seems "real" and the voices had a beautiful organic texture. In the same session I've heard also the Luxman 507ux ii and the MF Nu Vista 600, the first very analitical but also musical, the second extremely smooth and round but both lacks something in terms of realism compared to the 150. Speakers was the Opera V SE from the same Unison Factory I think. It will be great if you could make a review on the 150, and maybe compare it to your favorite gear that stands behind you! :) Congrats for your chanel and reviews
Upon your glowing recommendation, I got this last week, and I love it! Your description is dead on. I also paired it with my Denafrips Ares II DAC and it's a match made in heaven. The imaging and layering are truly remarkable.
Sounds like a nice match. Which speakers? And how does the amp sound at 90-95db?
@@JPWinters KLH Concords which are like 94dB efficient, so the amp hits dynamic peaks over 100dB no problem. I normally listen at like 70-85dB average.I wouldn't know for 90dB average as it would hurt my ears too much.
I have had one since 2004, a delight. My very best hifi buy.
My NHS hearing aides, had me in rapture, so much fades away, over time, that it becomes the norm. Its return shakes one.
Damn those Italians and their gorgeous workmanship. The Yamaha as1200 and kinky studios ex-m1 are totally different in terms of sound, but worthy competitors as well. So many good choices in the Under $3k price point
It's a great time to love music and the gear that makes it sound awesome!
It’s Italian, so there’s pride of ownership
I bought a Unico in 2006 and have never regretted it.
They way you described it, the Unico Primo sounds like a perfect amp for my Wharfedale Lintons!
It really would be.
I was thinking how it would be great with my Denton 80th Anniversary, which is even more rolled off then those Lintons, or the Denton 85th Anniversary editions. But yea, it would be great with anything from that line, and probably the Diamond line too. Which I also love. Wharfedale speakers definitely don't get enough love IMHO. ✌️
Did you buy the Unico for the Lintons?
This Review was NOT sponsored by 'Wild Interiors'. That said, I kinda wish it was. :D :D
What the heck is a " wild interiors"
No biggie! Opened cover’s more than enough! Who cares about the other interior? 😆
Aw man...! For the KLH model 5, this or the Yammy as1200?
@@fetaface1203 I got the Unico Primo It was a good match but I did not had Yamaha to compare with. Now I got the upgrade bug again and I am selling the Unico with the KLH.

you got me with the mozarella part already
Do you intend to test Unico Due ?
Sounds like something that I might just have to audition. Thanks for another great review!
Look at this, read the reviews avahifi.com/collections/solid-state-power-amplifiers/products/set-120-control-amplifier
@@jamescox4823 Honestly James. Having owned AVA products before, and not being very impressed at all. I seriously doubt that's anywhere near the SQ of this amp. I mean we're talking an actual tube preamp, with actual gain. Versus just adding more gain to an amp, and calling it a passive preamp. I'll take the two separate gain stages myself. All day, every day, and twice on Tuesdays. Thank you very much.
Besides, it's a completely different sound signature anyway. Not to mention it's not made in Italy by a company that also makes $50,000 integrated tube amps. Sorry, but it's just on a lower rung. And while sure, many people will like it. How many will honestly like it better then the Unico? Besides Frank Van Alstine I mean. 🤣🤣🤣
@@amb3cog You are wrong, you need to listen to this amp. I have many amps including pure tube ultra valves and this one is categorically better. Do a little research, read all the reviews on this. My guess is you think B&W speakers sound good?
@@jamescox4823 Whatever you say Troll! ✌️
@@amb3cog So I call BS on your OPINION and the name calling starts! So now that we have established you are an opiniated snob we also know your political affiliation. Again I have several tube components and this amp is really good, esp paired with my Dennifrips DAC.
Have you tried it with the KLH Model Five speakers?
This is a great video. Very interesting hybrid amp. does anyone know how does this Unico Primo compare to the Heaven11 [Billy] hybrid amp in terms of sound stage ?
Oh, you’ve popped the hood again! That’s romantic! 😁 Great review!
Great review, thanks. I have Unico Primo with Monitor Audio Silver 500 7G and I have a great sound for my taste.
Now i’m serching that tube, but from technical specification from factory the original tube is ECC83 (12AX7) and not ECC81 (12AT7), how did you manage to use that valve?
I think it's beautiful. I love the looks of it. I just wished it had more power. I'm really looking to move up in the power department. It's ironic that you also show the M6si, as that has been my main choice, UNTIL, they started making the M6 500si again, which is what I really want.
Great video.
Thanks
Mamma mia che recensione fantastica! Love from Italy!
PS I hate you guys a little bit, this amp is more expensive here in Italy than in the USA. Brutti stronzi!!!
Hi Sean, great review. What's your opinion on the Unico Primo over the Kinki Studio EX-M1? Which would you rather keep?
Still one of the leaders in my book
Definitely need audition after seeing this, Bravo indeed! How would you rate if this is to pair with KLH model 5? Would it be too much of liveliness as compare to your favorite pairing using Yamaha AS1200?
Surprisingly enough - it's a very good match. So long as the treble switch on the KLH is on the minimum setting.
@@ZeroFidelity: preference: Unico Primo or Yamaha A-S1200 to pair with the KHL Model 5?
Interesting. I had the original Unico (before Primo) with dual tubes in the preamp and absolutely loved it. I decided to switch to the Primo because it had a sub output and really regretted it. I really struggled with the harmonics in the high frequencies. Made all my music sound digital (even after rolling the tube). Especially evident on my Totem Rainmakers.
Thanks for sharing! I confess to purposefully omitting a fact from this review: I owned the original Unico. :D. I decided to say nothing as I know tons of people would expect me to recall an experience I had with a product from over 10 years ago as though it were yesterday. That said, what I do recall matches your experience. The original had a softer top-end and more of a romantic sound. It was extremely pleasant to the ears! Most of the time anyway. The problem was that the original homogenized the sound and wouldn't be happy with certain genres of music, like say, rock or electronic. The Primo seems more resolute and happy to play any form of music, with the tradeoff being that boost to the HF. I could see it not playing well with those Rainmakers or most speakers with metal domes.
@@ZeroFidelity Still have the original with two tubes. Was warmer, more organic, soulful and funky. As far as volume and Rock? I dare you to listen to the Allman's "At Fillmore East" through that amp. The Kevin gray rendition will knock you down with tone and color! And that's through a speaker rated at 86 sensitivity. Sound did remain warm at volume and sounded robust. Still running original military grade Phillips tubes!
Reminds me of 1st Puccini amplifier from AA. About 2 decades...
Interesting review! How would this compare with, say, Marantz Model 30? I know there's no tone controls but I wonder how the phono stage compares for example? (Looking to upgrade from a Yamaha AS-801 here)
Hi mate greetings from Australia.
Im going through the process of building up my 2 channel system, My first purchase was a Avid Sequel SP turntable with a SME Series 4 tonearm and 2M Bronze cart, phono stage is Simaudio MOON 110LP V2.
Have just bought The Unico Primo which will replace a Sansui G-7700 powering a pair of AR94's which have been recently refurbished. I'm thinking of replacing the AR's with a pair of KLH Model 5's. In your opinion will these speakers add an improvement and will they pair well with my system.
Cheers Enrico.
I bought a Unico Secondo used with an installed pair of RFT tubes...and I'm very happy with the sound... lush and satisfying os what I describe it..
Wondering how much different if I change it to a pair of Gold Lions.
Sean, there seems to have been a power supply upgrade on this model. The previous one has this curved heat sink around the transformer unlike the rectangular one in your sample. It also does not have that protective casing with Unison branding around the transformer.
Some online stores talk about this and mention, how Unison improved the dynamics, bass performance with the upgrade which also included the caps.
Do you have a view on this. I am seeing some 2nd hand options coming into the used market with the older PS. They pair with the RC2 remote. So I am assuming they are not the previous generation model pre 2011.
I wonder how this would compare to a hegel h95. Does that tube make a worthwhile difference?
It is a nice piece of industrial design.
it looks delicious inside
Do you have any experiences with the Unico 150? Might it be comparable sonically with more oomph?
Are you going to review the Dynaudio Contour 20i?
How about a shootout between this amp and the Audiolab a6000 ?

Hey Sean - great review and I appreciate the work your doing. I was wondering if you thought the Unico Primo with the tube roll would work well with my Klipsch RP8000F?
Can you define "loud volume" a little more? You say rock concert, but is that above 90db? Also, could you use the Tape Out to run to a headphone amp? This with the Sonus Faber Lumina II's?
Addressing your questions: 1) I can't define loud in DB for you, as quantifying that number will hinge on the speakers you use, the room you have them in, the distance you sit from your speakers, and what your ears consider to be loud. So to keep this simple, I'll say this: If you want to listen at volumes above 90dB with the Unico Primo and DON'T want your ears ripped off in the process, you'll need to use power sensitive speakers from the likes of say, Klipsch or Tekton. 2). I don't believe the TAPE OUT will work. You'd have to consult the manufacturer to verify for sure . Having said that, the low-impedance out (labeled 'sub') should work. 3). I'm guessing the Primo will sound good with the Luminas based off of what I've read about those speakers, but since I haven't heard the combo, I cannot say for sure.
@@ZeroFidelity you’re the best!
Hey Sean great review. I have been considering the Primo lately and am wondering if you have heard the Billie Mk2 and if so, how would you compare it to the Primo?
Hello Sean, first time commenting on your review and I love it. I have a UR unico nuovo, an older model but the inside is pretty much the same layout. I noticed that you said you didn’t have the phono stage but if I’m correct, if you had the top of, directly behind the tube is a small print plate vertically mounted. In my layout that is where my phonostage is connected. So isn’t that the phono stage in your amp as well?
Great review! I love my amp and if possible will se if I can update to the bigger brother. Thanks for all the details and the work in your video’s. Love it.
Peace…
Hello. What speakers do use with this amp? I have the same and I'm looking for bookshelves that will be the best match. Thank you.
"AY, TONE!" Disappointed you didn't do this review with a Paulie impression from Sopranos.
Dang! A missed opportunity.
@@ZeroFidelity hi, I want to buy this amp , please tell me that KLH MODEL 5 is appropriate with this amp
The assertion of the high end could be due to tube compression. The beautiful thing about tube’s non-linear response which is octave distortion. But frequency response effect occurs because larger amplitude sounds get more reduction, so highs are relatively louder. Do the compression at lower power, in the pre-amp, allows it to be done more precisely quadratic.
I wonder how it would compare to Dayens, like the Menuetto? (which, granted, is half the price)
One more great review Sean !!! Hello from Greece :)
You mention that the amp has elevated treble. My question is this: You always use a standard (external) DAC to review a unit ? Because if indeed true, this means we do not know exactly how fi the Primo performs since is effected by the sound of the dac. If not, you test with an analog source?
And you also compare the Primo with the m6si. Which dac is used with the Primo?
Just curious :) Cheers !
There is no DAC inside the Unico Primo.
My Cambridge CXA81 is my first and only experience with a decent A/B amp..and previously I only used class D amps driving active speakers, like my Sonos era 300s/Arc or Adam A7X monitors.
I’m curious about your point about the Primo not handling high dynamic range tracks well like a class D .. Is this typical of all A/B amps? Been listening to tracks with huge range on my CXA81+ Kef Q350s and it seems to handle dynamics as well as my class D gear (Cat Stephens: Tea for the Tillerman in particular has a lot of soft/quiet passages that suddenly shift to loads of energy)
Maybe my ear isn’t well trained enough to pick up these differences or nuances yet.
Enjoyed the review. I have the unico due with two 12ax7 input tubes. Do you think it would be safe trying two 12at7 tubes? I have a pair of Siemens NOS 12at7 tubes on hand…
I'm still using the original Unico. Similar to this, but 2 ECC82 tubes. I rarely crank the volume, but the sound does change when I do. Some people say it gets 'airy', I think thin.
I had the Unico SE with Triangle Celius ES since the early 2000's. A bit of a mishap forced me to swap my Unico SE with its big brother the Unico Secondo a couple of years ago. And when Sean made the comparison between Triangle's Australe EZ with the Forte III's, I decided to pull the trigger on the Australe since no one around here carries Klipsch's Heritage speakers. Couldn't be happier. Now I'm thinking that maybe I should look into tube rolling. It's a toss-up between the Golden Lions & Telefunken Black Diamond, both around $125 / matched pair.
I wonder how this compares to the Vincent SV-500
Jay - I'm wondering the same thing. I have been using the Vincent SV-500 for this past year and really enjoying it, but wondering if the Unico would be a nice upgrade!
@@timsdeskontask3958 Yes exactly. I also have Vincent (which hardly gets any attention) but wonder if a unit like the Unico is a vast improvement.
@@jaysworld5378 I have noticed the same thing - no reviewers are discussing the Vincent amps. As someone who hasn't access to a local store and relies on the comments of reviewers, I would love to see Sean and some of the other primary reviewers take some time to compare the Vincent SV-500 to other amps they've spent time with. As you mentioned, is something like the Unico Primo a big improvement over the Vincent, or are we needing to spend well into the next pricing range (like Hegel) to get that big improvement.
Sounds like it would pair up well with a high quality single driver full range speaker.
I repaired one and let me tell you that is one of the best sounding integrated amps.
Shawn. I think I want to try the Unison Research Primo or Due. Are we sure audio legacy is an authorized dealer for UR? Because I was on the UR site and they mention no authorized dealers in the USA. I wrote them directly so I hope to hear back from them, but if you know for sure please LMK.
Mark, I bought my Primo thru Audio Legacy but the real “Main Man” is named Boris (Filiated or Affiliated Electronics?) .. Hillsborough New Jersey.. He does all the mastery fixing if necessary and did tell me he’s the “Boss” & Owner but sells thru Audio Legacy.. Probably for tax purposes.. He has the Units here in the US & sells high-end power cables & other accessories.. If he runs out of amplifiers he orders more of whatever unit the customer wants , shipping them to his Audio Legacy on line store & usually gets it to you fast from there.. He’s very honest to deal with👍 If you call him (get his number thru Audio Legacy), to ask questions about his AL store tell him R. D.H in Florida sent you👍 You can also hear the Primo on my YT channel.. Hope this eases your mind.. And they have a return policy if you’re not happy, but I can tell you from personal experience, The Primo is Primo..
There is a substantial market in the USA for a) tube or tubey sound.b) lively presentation c) subwoofer output to compensate down low (and offload quite a lot of power handling to the powered sub, giving the amp more breathing room). Power? 80wpc is still enough, but not for a "party amp".
How does it handle current capability and crazy speakers that go down to 2 Ohms (sometimes even less)?
How is customer support? When you plonk 2000 down you have to bear this in mind.
HI, juste discovered your chanel and like it a lot even if you speak very quick some tims ^^
Could you compar it to the tsakidiris Aeolos ? That would be a very intresting comparaison for sure
Thanks anyway
I have the Musical Fidelity M2si. Should I try the Unico Primo instead with Buchardt Audio S400 mkii ?
@Zero Fidelity
Sir, would you mind giving your two cents on the Unison Research Unico Due Integrated Amplifier?
I'm looking for a dual-mono or stereo amp to drive Focal Chora 826 tower speakers.
Where are you seeing the Gold Lion tube for $36? Best price I could find is $65.
Duuude that Italian accent, genius! 😆
Good review, but not at all a revelation as Unicos have been rated highly by reviewers and users for years.
If you need more grunt and db's then get the Unico Secondo.
I have used one for 11years and absolutely love it. Tests at over 110w into 8 and 180w into 4 ohms.
Has driven ATC, Kef Ref one-two and currently Canton A45 without breaking a sweat.
Beautifully built with dynamic, balanced, detailed SQ. Cheers.
I have found your comparison with the M6si the most intriguing part of the video.
Considering there are some similarities in their respective sound signatures with the higher registers being slightly elevated, would the speaker matching recommendation for M6si be similar as well: e.g. Buchardt Audio S400, Dynaudio Evoke Series, Harbeth, etc?
Thanks and keep up the good work 👍
Very similar in terms of ideal speaker matching, yep.
I had 3 integrated amps: Naim Supernait 3, M6si & Unico Primo (with the stock tube replaced by a GE 5751). Tried all 3 with my Harbeth M30.1. I sold the M6si as I found it had too much grit in the trebble and the soundstage was too forward. The Supernait 3 is now paired with my Martin Logan Montis in another system while the Primo is happy driving the Harbeths. This is one of the most underestimated integrated amps out there... if you replace the stock tube...
@@danielblais5047 do you think the primo has better sound quality then the supernait 3 ?
@@enjoyunreality That is a tough question. I think if you factor in price: yes. In absolute terms where price is not factored in, I think the Naim is more revealing and has more drive, especially with harder to drive speakers like my Martin Logan Montis. I now have a Gold Lion tube in the Primo and I think it makes sweeter with small jazz ensembles or vocal music. At more than 2X the price, you have to realy dedicated to go for the Naim instead of the Primo...
Nice review! Would a Subwoofer compensate the lack of power? Not sure if my thinking ist wrong
Sean, How does this compare to the Kinki integrated you reviewed in the past? My speakers are a pair of TEKTON Lore Reference.
Erik. I have the Tekton Lore Reference speakers as well. I’m using a Musical Fidelity M2si integrated which I find slightly on the bright side.
What amp do you use?
Thanks!
@@gcsoundscape I am now using a Kinki Studio with CSS 1TDX and very happy with this synergy.
Hi Sean!, Excellent review BTW. How would you say the Unico Primo compares to the Yamaha A-S2200 in high-frequencies performance and in overall sound. I am looking to buy an integrated amplifier and want something for upbeat tempo music such as rock/jazz fusion. I don't like smooth rolled-off highs.
