Jfets are often used in phono pres for the MC step up. That’s how it is in my Tavish phono pre. As good as it sounds, using one of my LOMC’s through a SUT first into the MM section does sound “better” I understand what you’re saying Steve, and have had a very similar experience.
Steve -- I've used SUTs for years, almost exclusively. I agree with you. As you say, an MC cart requires two stages of gain. That first stage can be accomplished with an SUT, a transistor in the phonostage, OR an SUT built into the phonostage (CS Port's and Nagra's phonostages do this, for example). What it took me years to realize is that many, many "tubed" phonostages actually run your MC signal through a solid state transistor first (Audio Research, for example). I bought my first SUT simply to bypass the sonic imprint of a transistor (as an experiment), and it led me to a place where I now own 15+ carts and 15+ SUTs. Borrow one whenever you like. But there are a few camps out there on the adjustable SUTs like Zesto's. The magic of the very best SUTs is in the artisanal windings of the actual transformer, and that artistry can get overshadowed by monkeying around with variable impedance, variable gain, etc.
Steve ~ As to why most step up transformers increase dynamic range better than active gain stages has to do with the ability to transform the moving coil's low voltage, high current input (via a low impedance primary winding) to the high voltage, low current output (via the secondary high impedance winding).
It does this by 1) conserving input to output power passively without adding noise, and 2) having unlimited slew rate by over-designing the transformer's magnetic core material.
SUTs I use with my vintage Ortofon LOMCs are:
• UTC Ouncer 01 w/ MC-10
• Lundahl LL1941 w/ MC-20, and
• Triad JO-3 w/ LYS.
IMO, SUTs get the most out of LOMCs.
Steve, this was awesome. I had always assumed SUTs existed as a workaround so you wouldn’t need to upgrade your phonostage. Very educational and unexpected!
I love this channel and this video is great because it reflects the resurging interest in vinyl. I recently brought my old Linn Axis turntable back to life ( a very difficult repair) and have been rediscovering the delights of cartridges and phono stages.
Oh boy! More variables! Why are you trying to get me divorced?
Step up transformers (good ones) are wonderful. I have used head amps as well, which might be more transparent, but there’s something about a transformer that adds to the musicality of the cartridge that I prefer. I’m glad you were able to discover the magic that a good step up transformer can add to the vinyl playback experience!
And they do sound different, I’m on my third or fourth model of step up transformer, with this time using Bob Device‘s Sky transformer, have a pair of David Slagle’s transformers he made for me that I need to rewire to get rid of a ground buzz issue, both transformers sound different from each other. The Slagles are a bit more transparent but have a lower output, while the Bob’s Devices transformers (custom made for him by Cinemag) have more of a sense of body and drive to them.
I agree i discovered this the hard way i had a Conrad Johnson Premier 15 with a Koetsu Rosewood standard and a VPI Scout and a step up transformer and that combination sounded better than a 20 grand phono without a step up. A step up adds meat on the bones and dynamics and makes it sound more alive period and less 2 dimensional they work well in the right set up.
Steve, It amazes me it took you so long to realize how much better MC step-up transformers sound over high-gain active preamps. I experienced the same thing 20 years ago with my Benz Micro L0.4 cartridge, a relatively high 0.6 mV output. I had a vintage Audio Interface MC transformer (still have it) CST 80 (20 db passive gain) which I had bought in the 90s with a Dynavector Karat Ruby (also a high coil impedance cartridge). I was blown away by the warm, luscious, lush, addictive sound. The L04 had similar electrical specs as the EMTs so I bought an EMT cartridge and thats heaven. Linn has a new cartridge (the Kendo) I understand made by EMT with the same specs: 0.6 mV output and 12 ohms coil impedance.
For your XX-2 (6 ohms) I suggest you try the Dyna's own transformer. It also works with Ortofons and Audio Technica. For the Zu (Denon), Denon transformers are the best.
The AI CST80 is considered one the best MC step up devices, comparable to the legendary MA Cotter. For Benz, EMTs, Denons, Dynavector Karats, Van Der Hulls. There is one on eBay right now at www.ebay.com/itm/225612746732
Been using SUT's for years and they are a game changer.
Quality of the SUT matters.
Going to have to rewatch this episode a few times. Lots to consider here.
I use the ELAC Alchemy PPA-2 for great clarity, detail and dynamics.
I do not play vinyl, but your enthusiasm is very inspiring nonetheless. Always enjoy watching your videos, it makes me listen more.
I have since 1982 used an Audio Technica AT-630 For MC Cartridge Step-up Transformer for my Nakamichi MC1000 reference pick-up on my VacuumState FVP5a preamplifier that never had enough gain. I have recently (2yrs ago) purchased a JLTi Phono moving coil preamplifier which has taken my vinyl setup to new levels of charity, wider soundstage and in your words a more there, there experience.
I was happy with the step-up transformer but was total blown away by the JLTi phono preamplifier in my system.
Great topic Steve! It’s worth noting that the SUT’s turns ratio needs to match the LOMC’s impedance, and that there’s a calculation to figure that out. Also, another phono cable should be used between the SUT and preamp, not just a regular interconnect. Because this is typically an RCA to RCA connection and most phono cables have a DIN to RCA connection, this is a common mistake.
I use an Allnic AUT-2000 SUT with four different gain settings, similar to the Alesso. Up until now I’ve used it with the MM input on a Luxman EQ-500 and an EAR Yoshino 868 pl, both of which also have LOMC inputs. I agree completely with your comments that SUTs are more dynamic and plump up the bass. Even though both the Luxman and EAR use transformers, the Allnic is noticeably better. As passive units, as long as they are placed away from power sources, they are also incredibly quiet, which I believe aids the sound presentation.
I like SUTs so much that I’ve just ordered a high quality MM-only phonostage, a Lejonklou Slipsik 8, to pair with the Allnic. I’m totally sold on SUTs and may purchase several more in the future. The MM/MC phono preamps will go to new homes. They just aren’t needed!
You know your stuff. Thx for sharing your knowledge. I'm so new to this.
The cool feature of SUTs is that high frequency brightness can be compensated by putting load resistors across the secondary winding. Parallel resistance provides HF roll-off. Ended up with 165KΩ across the UTC Ouncer 01, and 110KΩ across the Lundahl LL1941s. The Triad JO-3's didn't need any ~ they sounded fine w/o any :)
SUT's are the MC secret sauce. The reason is simple, there is no power involved. As long as they are well electrically isolated, they will always be THE right choice. An important point, given that they introduce another set of cables to the loop, shielded RCA cables are an utter necessity, or you'll have another antenna for electric interference. Ortofon makes some excellent ones exactly matched to your Ortofon MC's. The improvement over McIntosh C53 internal MC amp (which is superb itself) was definitely noticeable.
Great video Steve! Have not heard anyone else cover this topic! Definitely opens up another avenue of investigation. All those with integrated amps having MM phono only can really take advantage of this without having to go down the separate phono pre amp route!
True!!
Glad you rediscovered SUTs. I've been using a Bob's Devices "Sky SUT" for about a dozen years with my Ortofon Cadenza Black. My phono stage is the well-regarded EAR 834p Deluxe MM/MC designed by Tim de Paravacini but the MC is dull and lifeless. All that goes away with a great SUT in play.
Cool, I use the same combo (Sky SUT/EAR 834P) in one of my systems, very good performance for the money.
You do know that the 834 uses a SUT for its MC section, don't you?
@@razisn You obviously don't know that the 834P also comes in a MM ONLY version. I've owned both of the 834P models. Do a little research, it might help you understand better, just a thought.
@@razisn Yes, but the quality of the transformers or their implementation is not good. Not just me, but almost every review mentions it. And Stereophile lists it as Class A in their biannual rankings but singles out that the Class A rating is just for the MM section even though the model they are discussing is the MM/MC model.
Very interesting. I'd never seen a review comparing step-up transformers although I've read some discussion on forums. Thanks!
Great review! Very educational. Down the MC step up transformer rabbit hole I go. 😂
Great video, Steve! I use a Rothwell MCL SUT in conjunction with my AR XA table and Ortofon Quintet Black S cartridge running into my Plinius 8150 MM input. Sounds great! Deep and muscular with not a hint of noise.
Hi Steve 😊
Yes i have a pure Sound p10 sut and i have precisly the same experience as you, nice input Steve 👌
-Thomas
Okay Steve, now I'm going to have to check into step up transformers. As if I needed to spend more money on my system...lol. Like so many of us, I'm always searching for that better sound. Your enthusiasm over what these transformers bring out in the music with moving coil cartridges has lite a fire under me. As always, love your videos (although my wife might not appreciate them).
'
Thanks for this Steve. I'm a DIYer that plays in the digital space and I've been having the itch to get some vinyl. This might be something to have fun with and a departure to my comfort zone.
There are some things in audio I disagree with you on but you always have a nugget that makes me go "hmmmmm" and try something new.
Thanks!!
Great video, I have been aware of SUT’s but no one has ever mentioned that they could give superior performance over an MC input. Thanks for pointing this out, I will have to check this out.
Seasoned audiophiles have known of the superiority of mc cartridges and SUT's since the mid 70's. I bought my first SUT in 1977 to use with my GAS Sleeping Beauty mc cartridge - Verion/Cotter P SUT.
The clarity and sense of increased presence you hear with the step up transformers is the exact same change you will hear when moving from resistive volume controls to transformer based volume controls. When I put a pair of autoformer attenuation in my 300B SET amp. It was like lifting a couple bed sheets off my speakers. I would recommend them to everyone.
I just ordered a Rothwell MCL SUT for my system - looking forward to it!
What!! You show that wonderful setup in England and I didn't even get to hear it play? Great Video, thank you for posting it. I have a few old suts, from Radio Broadcast stations. And a few transistor mc to mm units from radio broadcast stations. One day soon, I hope I will get them all configured and set up.
6 months ago I bought my first MC cartridge. Rega Ania MC for my Rega Planar 3 to replace Ortofon Blue 2M cartridge. Almost immediately I researched how to get the most from my MC cartridge. I read about step up transformers and was interested. After watching Steve, I'm going to find one.
Moving coil step-up is not the only place a transformer can improve your musical experience.
I use a passive pre-amp. Not a pot, not a resistive ladder but an audio auto-transformer. The electrical difference is that lowering the volume with a pot increases the output impedance but using a transformer lowers the output impedance. The upshot is that there is less difference in character of different interconnects. The sound is different to anything else and (to my ears) very musical. If you've never heard this set-up (often referred to as a "magnetic preamp"), I'd suggest you owe it to yourself to try it.
One version of the Ortofon SPU cartridge brings the transformers built into the headshell. Magical! But this brings a large mass into the headshell, with its own set of extra considerations..
I have been using tube phono preamp for as long as I can remember and step up transformers are pretty much your only option for using Mc cartridges. I find this combo works best for me.
I'm using a DENON AU-320 step up transformer with a low output Benz Micro Reference cartridge, going in the MM tube phono stage of a Sunfire tube amp, and the sound is amazing !
I’m considering that SUT for a Denon DL-304 cartridge. It should be spot on for it, but my concern is that old looking cable with plastic RCA plugs -I would rather use my own low capacitance cable. Did you find any problem there? Is the cable well shielded in your opinion? Thanks in advance!
Super interesting stuff Steve. Thanks.. Definitely a new wrinkle to your enviable portfolio of stereo equipment.
Food for thought, Steve...I use a low output MC and have been occasionally flirting with the idea of SUTs, maybe now's the time for me to get more serious! Cheers from London, England 🇬🇧
Greetings Steve!, This is the O.G Black man music lover and audiophile. I enjoyed this video very much. My audiophile world has taken a revelatory hit lately. Last November I purchased a Grado Opus 3 cartridge and used it with a Sota Comet turntable. I recently switched to a used Sota Sapphire that was just as old as my 30 year old Comet. The musical gains have been astounding across the board. I just couldn't stop wanting to keep playing vinyl. The secret was in the sprung suspension inside of the Sapphire versus the mass density used in the Comet as in the Technics 1200 I used to own. I'm sold on inner-suspension turntables being superior in sound (as I always suspected) to those that rely mass plinth loading. This technique will allow any cartridge to do its job better and extract all the musical information in the grooves( possible pun intended!)😁 of the record. It doesn't matter what music I'm listening to, Jazz, Classical, Rock, Reggae, R&B, (some hip-hop) Blues and etc, the Sota Sapphire/Grado Opus 3 combo just soars musically. The Grado Opus3 is also the best cartridge I've owned, easily equal to and in most cases better than my former moving coils! This has been a strange yet enjoyable experience to this seasoned audiophile. How two components with 30+ years between them can create a great musical synergy?!👍👍
Thanks for sharing!
As much as I appreciate your channel, no more heeding your advice. Aftter your rave review of the Technics SL 1200G, I found out from personal experience that, that was all, in my opinion, hype!
I have handmade tube MM phono preamp using it with Rothwell MC1 Denon 301 MKII cartridge and SL-1500C. Lovely sounding combination
I'm still using an audio technica AT 650 step up transformer with at oc 3 cartridge. Sounds superb , 40 year old transformer with variable impedance settings and silver wired internally. Fetching high prices on the second hand market .
Really great video Steve. It inspired me to trial a couple of SUT options with my Hana ML + Dynavector P75 - a Fonolab EQVES and an Audiitorium 23 (Denon 103) SUT. Wow...what a transformation. The Fonolab produced similar results to what you described with the OJAS unit, but got a little congested at the top end. The A23 was spectacular top to bottom and the one I have kept. Matching SUT to cart is definitely pretty critical, but on paper the A23 should not be an ideal match for the Hana ML - proving that auditioning is the only way to go.
I was lucky enough to acquire a Kondo Audio Note silver wire SUT, and it is amazing. Even though I couldn’t use it with my high-gain Conrad-Johnson phone preamp, it’s still awesome feeding my much more affordable Sutherland KC Vibe.
I repped the Nagatron HV-9100 Ribbon cartridge when it was introduced in the "70's. With a 0.04 mv output it had a massive matching transformer required for it.
Steve- you surely remember the SPU cartridge WITH Integral Transformers INSIDE the headshell. Magical, but HEAVY Headshell. The AR turntable needed an extra DEDICATED counterweight supplied gratis by AR when requested.
30 years ago I has a Koetsu transformer, clad in a cherry-wood box. It was terrific.
Very good reminder of how we change things only to realize that we had it right at the beginning.
real good video! enjoyed, have to re-watch. Have some S&B TX 102, and 103 in box somewhere. should try them again
I don't own any MC cartridges and most likely won't be buying one anytime soon, but here I am listening to Steve wax on about MC step up transformers because Steve you're an enthusiastic, knowledgeable and entertaining guy! I always learn something.
Thank you! That's so nice to hear.
@@SteveGuttenbergAudiophiliac Thank you
In the 90’s, my company, Expressive Technologies, made a very special step up transformer. It was highly praised by Steriophile and TAS. We sold a modest number of them.
For reasons that I won’t get into here, it’s very difficult for active circuits to handle extremely low voltages well. Even though the transformer adds an interconnected and itself, the benefit of a 20X voltage is significant and easy to hear.
I agree! After a music signal passes through an SUT the signal-to-noise ratio is superior to ANY mm or mi cartridge. The result is more life-like detail and dynamics from familiar LP's.
I have been using mc cartridges and SUT's since 1977. My first pair were the GAS Sleeping Beauty Super Elliptical mc cartridge and the Verion/Cotter P transformer.
Watching Steve's video's are getting expensive! I just bought a step up transformer because he really piqued my curiosity about how much better MC cartridges can sound using one. I have a Lyra Delos cartridge like Steve's, which I think sounds amazing as is. I guess we'll see once the SUT arrives whether or not I hear a marked improvement. I will update in a week or two. Thanks Steve for the great video's. Keep up the good work.
Yes, please let us know!
Have a Rothwell MCX into a Vertere PH1 (phono stage) through a Sumiko Songbird LOMC. Phono: Rega P9 with Origin Live Silver MK 2 tonearm. Liquid sounding but not too mushy. Thank you, Steven!
Excellent video Steve. One of your best for me personally. I also use a Dynavector xx2 into EAR 834p. I've heard this phono has good transformers within but there is also a separate step-up, the MC4 which I've wondered if it would be worth buying?
I had the same revelation switching from an MC phono input, to an Altec 4722 SUT with my SPU #1 also! However I found that my Denon 103 works better with Altec 15095 transformers. A definite night/day difference regardless. Nice one
After so many years I went back from MC tot MI cartridge. One of the best that is. I never looked back. MC always sounds more like hifi to me. No matter what or even if I don’t hear it in the short run. It is always there in the long run. So MI is where I will grow old with.
Which MI did you go with ? Nagaoka ?
I can be a little slow so I'm not understanding what you're saying. " MC always sounds more like hifi" - this is bad in your opinion? MI = moving iron? Are you saying it sounds less hifi and more like music? There are low output MI carts so wouldn't they benefit from a SUT? Are you using Grado or Soundsmith or something else? Sorry for all the questions.
Same here, moved from a VdH MC to a Nagaoka MP500 so I could use the very tasty MM only tube RIAA in my amp and I'm a total convert to Moving Iron, really seems to be the sweet spot between magnets and coils
@@tallcat576I bought the last cartridges of ‘the cartridgeman Musicmaker’. I would now look out for Soundsmith.
I was fortunate to have bought the last two moving iron cartridges of the cartridgeman. If I would now be into something else I would look at Soundsmith or grado.
It’s a little bit harder to catch in words why MC cartridges do not stick with me. All equipment always has some signature that is left behind with the listener after a long period of listening. I find MI or even MM to be more emotionally involving. Just music and no hifi sound. Maybe that has to do with the midrange maybe it has to do with MI sounding more ‘dirty’ in a way. Like when you’re playing some steamy jazz or some blues and you wanna feel it and not just hear it. With MC I often miss something even though a lot of people consider MC as better. At least technically. Maybe this explains a bit more where I am coming from. I consider it nuances but like I said ‘it is what sticks on you in the long run’.
Reading The Audio Critic mag in the late seventies early eighties they were all into passive SUTs as opposed to active MC stages, as the very best way to boost the signal from your MC cart of choice. So it's far from a new idea and I've been using these ever since. MCs electrically vary so much when comes to their different needs, that to extract the utmost out of your cart you really need to have a specially dedicated SUT for each and every one of these. OR as I do; have a very versatile Kondo AN Japan all silver S-7 Cz transform with a captive AN silver IC cable. And boy do it sound differently according to the settings. And absolutely glorious when hit bulls eye.
So if you have a lot of different MC carts it is wise to choose a variable Step Up Transformer
I agree! I too subscribed to The Audio Critic! My first SUT was the recommended Verion/Cotter P SUT.
straight wire with gain, I suppose the host didn't want to sound trite, but I'll repeat the conceptual ideal amplification, and I would say the passive amplification described here is about as close as one is going to get.
I was pleased to find that my understandings aligned with the expert host's experiences. I run only a single MM cart for ease of amplification, so have only that experience. But it only stands to reason that a simple this or that phono voltage amplifier is going to have it's limits, so I've been sticking with my nice MM cart and replacing the tip when it wears, knowing that a stronger signal will get processed less. Plus my records are mostly rock and simple to record stuff, so I'm fine. everything sounds good.
But this presentation reminded me how best to set up a low output cart, and although I have been thinking about upgrading my amplification , I haven' t really been thinking of transformers , even though I knew they were the best way to go. .
I don't switch carts , so I'll just have to find one optimal match transformer, if I don't stay with high output .
I have never heard a mm or mi cartridge that can compete with a lomc cartridge/SUT combination.
All the SUT's do have their own "flavor/sound". That's why I own several. My latest SUT purchase was the Mike Sanders Quicksilver.
Thanks for the video, I thought I was happy with my JC3+ and Hana Umami Red. Now I have to try an SUT, I foolishly keep thinking I have completed my system.
I'm definitely curious about hearing a SUT in my rig. Viewer system of the day is cool but also that Travis Bean guitar!
This was fascinating. As others have pointed out, the constant among your variables was the JC3+. I would be very interested to hear commentary by John Curl himself and/or other phono preamp designers --- those who use built-in SUTs in their phono preamps and those who don't. As you suggest, here must be trade-offs.
EQ differeces either intentional active in the preamp or R C L interactions in the inputs and outputs of the cartridge and transformers.
Congrats Steve, you just put the big-buck unit mfgrs on the soup line😳🤯🤣.
Steve, great video man. 1 thing though, with Ned’s bases you’ve got that same ability to use 4 different gain settings. Add a Darlington Labs MP7b with many different load settings fir a lot less than the Zesto…..anyway, I’m an analog fanatic, so loved the video😊
Sorry, should said Ned has another base, which I have, that has 4 different gains…or 4 winding ratios, however you want to say it.
Since I use MC cartridges I also use a step up transformer, my choice is a Phasemation T-300. Cheers from Germany
How true. There are some awesome SUT's out there. For instance the HEAD TX4, best bass in the business, Stevens and Billington silver, great value high end, and the better Audio Notes, i.e. S8, and Kondo SFx. In general, counterintuitively, it's better to spend more on the SUT than on the cartridge imho.
You may be right about spending more on the transformer than cart!
I use a (very low) output MC cartridge (Audio Note IO Gold) and a SUT is essential to boost output enough for pretty much any phono stage.
Hi Steve, thanks for your reply. Not quite sure what you're trying to say though?
Oh man......now you've got me wondering what I am missing out on :-D . I'm using a Hana Umami Blue, directly into a Manley Chinook.
Steve I have three Six Acoustic “ York “, phono stage now, getting big brother Belmont.
I should’ve never sold my Koetsu step-up transformer. Hindsight is a perfect science.
I regret selling my Verion/Cotter P SUT some decades back!
One of the best cheap setup I done was to use a Cine-mag (same brand as OJAS) for my Denon DL103/103r with a cheap Schiit Mani RIAA stage. I think the Schiit Mani sound to bright as it is (both MM and MC) but with the Cine-Mag transformer it got that bottom punch and at the same time get the clean sound from the IC OPA amps. It is a cheap way to start using transformers and the Schiit Mani is so good and cheap that you still will enjoy the music 100% when saving money for a real expensive phono stage.
Interesting talk - I’m sticking with Nagaoka MP110 moving magnet cartridges. The Nagaokas sound great with most any record and cost under two hundred dollars.
Moving coil cartridges have always struck me as finicky and expensive. To each his own.
Steve, you look like that keyboard player from The Sparks in this video :D
Dynavector XX2 MKII is great, it’s been my main cartridge for the last few years.
The way you describe the transformer as having a more expansive sound is exactly what I’ve experienced with transformers versus step up/head amps!
I also use an xx2 into an EAR 834p. I've heard this phono has good transformers within but there is also a separate step-up, the MC4 which I've wondered about.
Can you recommend one of the less expensive Dynavector’s?
Being a large inductor, a transformer would have some frequency related inductive phase shift issues active electronics would not.
For heaven's sake, Guttenberg, not only are you costing me a fortune, but you are risking marital disharmony in my home! So, I had to get one of these transformers, and you are absolutely correct - the difference is amazing. I tried with both a Quintet Bronze and the SPU #1E cart that I also bought on your recommendation, and both sound absolutely superb. Given the incredible difference they make, I am surprised that these transformers have such a relatively low profile in the audiophile world. So, another point for the Audiophiliac - thank you!
The only thing I haven't been able to make work for me, that I can hear, is high-end cables. I tried again when I was rewiring for the transformer, and I just can't hear any difference between some fairly pricey phono to amp cables and some mid-range ones. My poor hearing may just save my marriage!
The Denon "AU-300LC" is an Excellent Stereo Step-Up Transformer, which is inexpensive AND lovable. Highly recommendable...for little money!
Yes, I have one bought on eBay for $200. I also have the Bellari ($340) - excellent too!
AND the Denon DL-103 is a Specially Delectable Cartridge, in the market for several Decades!!!
Interesting discovery. Who knew! I thought the step-up process in MM/MC preamps was achieved by variable step impedance built in to the preamp. But as is so typical in hifi, separates just work better.
Try the Rega Aura MC preamp, my best choice of HiFi ancillary in decades.
My experience was quite the opposite. Some years ago tried the Ortofon T-2000/MC-2000/MC-3000 and our group universally panned the transformer.
I used a Supex SDX1000 moving coil cartridge but never found a transformer that sounded good with it so I used a Thorens PPA990 and I hooked that up to my Audio Research SP6. I used that for around 40 years and rarely heard anything better. I downgraded due to a bass feedback issue. I now use a Supex MM cartridge directly into my Audio Research SP6B and to me the sound is almost as good and my bass feedback issue is mostly gone. My Acoustat X speakers have incredible bass.
Some of the SUT you mentioned are worth more used than my whole system. But I can attest to how much of an improvement one CAN provide. Only heard it in front of a Graham Slee (IIRC), but I can't remember which one it might have been.
Funny thing this video came out. I’m waiting on a Denon AU-320 sut. I’m going to pair it with my Denon DP 59L tt fitted with a DL 103 cart that was modified by Vas Cartridges in NJ. I’m currently using a Puffin phono pre amp. I’m wondering if I should set the preamp to mm or mc with this combo. 🤔
Love, love, love an SUT with a lomc cart. My two carts are the two classics - the plain spu and the 103 with the aluminum body mod. SUTs are the Ned Clayton Cinemag 3440 h, AN UK S1, and most recently a sound practices Hashimoto HM3 unit. Love playing around with these carts and these SUTs. Specifically bought an Aric Audio mm only phono stage specifically cause it let me play around with SUTs. Devon and Resistor Mag were the online sources that got me thinking about SUTs. It’s a fun thing to tweak when the rest of your system is already pretty dialed in. 🙏🏻
Using a Hashimoto HM-7 with a Lyra Delos = pure bliss.
What cleaning system are you using on your records? This clip had a beautiful clean and lovely record on your turntable.
Nice coincidence. I'm four years into my vinyl journey, and was just thinking that just upgrading the phono preamp (needed for surre anyway) would be just too boring.
So what caught my attention, obviously having never heard them, are the miyajima labs SUTs. And then pairing them with the Synthesis tube phono pre, should make an exciting combo. Hopefully in a good way 🤞🤞.
And to be honest, especially with my Audiolab amp, vinyl sounds sometimes a little to "small". Getting now, after watching this, the impression SUTs are good bet to get the feeling of an enlarged performance
We are to say that some high-end manufacturers use built-in transformers for the MC inputs of their preamplifiers, instead of active high-gain sections. That's the case of Bryston for instance. No reviewers cover that, but the Bryston phono stages are among the best sounding phono preamps around. Also, we should do justice to those exceptional phono stages that manage to get great sound with highly accurate, high-gain phono preamps. There are some, very few.
Steve, have you ever listened to the Emotiva Airmotiv XT3 speakers ? I just tried to buy two but they are sold out. Are they worth waiting for ?
ps- I am a "mid-range" guy. Not a fan of low end. These speakers have TWO 5.5 in midrange speakers. omg. crazy.
I greatly enjoyed this episode, so thanks! I would like to know whether you have ever reached out to John Curl, the designer of that Parasound pre. Some of us would like to hear what he, the designer, might have to offer.
Steve try reviewing Rothwell Step ups. Steve you might be surprised incredible value for the average audiophile they work great with classic Koetsu ! They make music. That combination with my Conrad Johnson premier 15 and Koetsu Rosewood standard mounted on a older VPI Scout sounding amazing it beat a 20 grand phono stage i bought used at a much lower price without a step up! I regret this decision ever since i sold that set up .Conrad Johnson made one hell of a phono stage it beat my Aesthetix Eclipse with out the Rothwell using the same cart and table. The Rothwell was $450 msrp it was the one designed for carts 0.2 MV up to 0.6 MVs.
Welcome back to SUTs Steve! I use a Sunvalley SV-EQ1616D tube phono preamp like Herb R. uses along with a Bob’s Devices Sky 40 SUT for my Hana Umami Blue MC cart on my VPI TT. I also use this SUT with a Dynavector 20x2L, Denon 103r & Denon 103.
For my second TT (Pioneer PL-630) I use a Denon 103 MC cart going into Robert Morin’s Lounge Copla head amp (used by Herb R.) and then into the MM of the Sunvalley.
Great episode Steve!
Never use a multimeter to test a SUT or Mic transformer. The DC used in the meter is too strong and will magnetize the transformer. Built my own SUT's from parts salvaged out of an old studio mixer board. Too much fun.
With low output MC carts, I’ve had the best results with transimpedance (current) phono stages. I think Steve did a review on the Sutherland Little Loco or Phono Loco. Spectacular! But not versatile for multiple carts (MM or high output MC).
Those need a very low internal impedance cartridge to work well.
@@razisn I was fortunate to speak with Ron Sutherland and asked about that very point. While he did not offer up specific thresholds for what constitutes low impedance or low output, he did say that he’s heard of good results with higher impedance cart (i.e., AMG carts), but I cannot speak to personal experience. I have a Phasemation cart (.3mV and 4omhs-low) and am blown away with the Little Loco. Plus it’s basically plug and play.
Yes. I made a Phonoclone. Sounded great with a 7 ohm Ortofon but meh with a 10 ohm AT
i guess that MC preamps need a special attention to the first input stage that should have a separate power supply circuit, also separate per channel. if the output stage of the pre-amp hangs on the same rails like the first input stage that does the x10 amplification, then part of the output and also nonlinearities gets coupled back into the input. the decoupling of the power supply is probably the most underrated source of dirt. also when it comes to channel separation.
i am not sure if the step-up transformer has any benefits when the input stage is made well enough. it would be very interesting to study all the schematics of all the MC PREs, that you used so far and compare them.
i don't know if you would like this approach, but i would like to only have a linear amplification on the analog side and then go into a super fine 24...32bit ADC and do the RIAA curve digitally only and go through everything digitally including active speakers that do the crossover as well digitally.
when doing the RIAA curve, it would also be possible to play different records made from different manufacturers and let the computer then calculate a calibration profile, that is unique to every cartridge. for example a frequency dependent channel separation calibration.
no cartridge is perfect, you probably have a tiny bit of a signal on the right side which should only be on the left side and vice versa. these are simply drawbacks from the cartridges. but this could be compensated for by a digital algorithm and then you have more channel separation.
the same thing could be with nonlinear signal vs. the excursion of the diamond which then creates harmonics aka distortion. this maybe could be back calculated as well in the digital world.
just some thoughts.
Haha, I succumbed to this vid and bought a SUT. I’m running a Vertere Phono 1 Mk IIL phono stage - by no means an expensive bit of kit, but certainly not cheap. Went with a Deco Audio Step Standard (handmade here in the UK so cost is low as it’s supplied direct). Will see if it makes a difference!
Yeah please let us know!
@@SteveGuttenbergAudiophiliac Well, lived with the SUT for a month now. It’s been nothing short of revolutionary, just not necessarily in the area I was expecting.
So, this is the thing. I was getting a lot of hiss through the speakers when using the Vertere phono stage, prior to the SUT. I’d been playing with the gain dip switches to try and get a decent vol vs. Increasing the noise.
Since using the SUT, and obviously reducing the gains on the phono stage to match a MM, there’s still a decent vol, but no hiss! As a result, it’s not highlighting every little pop and click too.
I don’t know enough about the electronics to explain it, but it’s changed EVERYTHING! 🙂
Rothwell Step up Transformers made in Britain beats the big dollar ones! I found for $450 bucks it beat many 1000 dollar and up ones ! Great value for the money
I have a Goldbug Mr Brier which runs into a Music First step up and on to a Croft 25R phono stage. It sounds unbelievably smooth and detailed. But I also have a Decca FFSS MK1 which is older than me that I use straight into the Croft. Is the MC plus step up better? I don't think it is, I think it's just different. They are both absolutely superb. the Mr Brier is so smooth and detailed and it has the ability to let you hear every instrument in the mix clearly while not pulling the performance apart. But the Decca is just incredibly "live" sounding and the dynamics are out of this world, drum strikes can make you jump. I listen through headphones (Stax LR-500, Final Sonorous VI and Denon AH-D7200) so the differences are clear. In this hobby you have find a sound that you personally like. I have heard super systems at shows that to me have sounded laughably, excruciatingly bad, and budget systems that have blown them away in terms of musical enjoyment.
Right!
Try the Rothwell UK basic model 250 lb up to a thousand
you don't put a cartridge straight in the headshot I found that out recently you want to tilt it inwards a bit the inside groove is moving faster so you need to compensate that speed of the groove paire to the outside speed of the groove, not only that Wally has found I think it was 72% or higher, that the Zenith the styli is out by this much and that seems have no variation on price or manufacture of cartridge or even the same model every one is different. you can buy his Wally tool to correct this error and that means twisting the cartridge inwards, so if you just want to experiment to do it yourself half a millimeter at a time possibly even up to a millimeter and a half. I find if you put The cartridge styli Hangover point between the two screws you're about there just Mark up the vertical line of the screw head and is your reference. Twist move it slightly one way or the other it if needed. Give it a go!! Steve! You might need to adjust anti-skate differently as well don't forget anti skate pushes the canterleaver and puts the angle at the wrong angle zenith, anyway. maybe this has some bearing when twisting the cartridge because this usually corrects the imbalance in the cantilever, you should always really line up the cantilever down the center equal measurement to the Head shell centre not the body of the cartridge. this would be difficult I understand with non removable headshells you could use a mirror underneath! Anybody's trying it let me know what your results are ! always interesting. you should get it right after about two or three attempts but make sure the hangover or commonly used term pivot to spindle, using a hangover method is a lot easier and I think more accurate measurement. You can make your own tool very easily after you know what it should be for your given arm and pivot to spindle measurement. Find a bit of plastic that stiff that you can bend with a paint stripper or hair dryer even, to the given point and with a hot needle broken off anf and stick it through the plastic at that given distance making sure it's parallel 90 degrees, and not too close to the styli keep it 3mm away. I find it's more accurate maybe easier to use than the things you can buy, if you've got one of them you can glue a needle into the V make it a lot easier for you should already be set at 90 degrees
Very Interesting! I was just about to consider buying a new cartridge because mine lacks dynamics. The cartridge is a Soundsmith Zephyr MIMC and I have a PS audio phono preamp. Perhaps a stepup transformer would be a better solution. I might get one of the inexpensive ones just to try it. Thanks Steve!
Yes, try it.
