I purchased a TS120se about a year and a half ago. Love the sound of it after some break in time. Always thought my speakers weren't quit up to the task. So last year I had GR Research build and ship me a pair of NX Studio's that was the missing link. I have not had anyone listen to my system that doesn't have a jaw dropping moment. Including a buddy that has close to a 100K system. He is rethinking his life a little now LOL. This is truly a pairing that is really hard to beat . Even if I were to spend another 20 or 30k the improvement wouldn't be worth the investment. Thanks Thomas and Danny for creating such outstanding products
Funny timing - I *just* bought the Galion TS A75 and absolutely adore it. It's the best amp I have heard in my system and it's helping me get back into listening more regularly. Thomas is an awesome guy too - extremely nice, passionate about what he does, and responsive to questions. ...maybe I'll save up for the TS 120 down the road, but I'm very happy with the A75. Thanks for the review!
@@VisionCarrierDreamCatcher I am listening to three: A Denafrips Hades, a Gustard P26 with Sparkos op amps, and currently enjoying a Schitt Freya+ with LISST solid state tubes in the buffers and 1950's soviet 6n8p tubes as the voltage amplifiers. It sounds pretty awesome. Speakers are Philharmonic Audio Model 2's.
I definitely think it'd be cool if Danny reviewed amplifiers every once in a while, especially to see what he would recommend for his speakers. Great vid!
Thanks Danny, I like hearing your recommendations even if it's just pretty quick. A lot of us don't have the ability to try out multiple pieces of equipment in our own rooms that we are familiar with, so we have to do the best we can trying figure out if other people's experience approach a consensus before we roll the dice with our hard earned cash.
Decay structure! Yep. ❤ The overlap of multiple decays from various instruments, when that is present in the background on top of the attack, spaciousness and great tonal balance….. realism!
Thanks Danny! Thomas a great guy, glad to see the two of you work together and it is good to hear a non-reviewer's comments on a piece of equipment (or two). ❤✌️🙏
I appreciated this video and knowing how critical you are, it showed very high praise for Thomas's designs. I'd really like to see your extremes or servo subs reviewed by one of them. Kind of a nice colab.
Hey brotha! I’m 51 years old and have been a sound engineer since I was 14. Anyway I would like for you to review this speaker in my opinion this is the best speaker that I have ever used with just its internal passive. Crossover. It’s a EAW LA325 I have opened this speaker and the internal crossover looks insane!!!!! I would love for you to review that internal crossover it looks insane! This is the only pro speaker that I have ever used where you can just connect an amp direct and it sounds amazing! Very very smooth sound
Every component Thomas has released gets great reviews You doing reviews like this are a good thing so if you decide to do more that would be fantastic
It’d be interesting to get Danny’s take on the two speakers on which Dr Viet and Thomas have collaborated- particularly his thoughts on when a design is intentionally voiced to a profile that might not necessarily “measure well”. Out of idle curiosity, has anyone pranked him with the task of “improving” a pair of vintage Rogers LS3/5As?😂 Cheers, y’all
Nice to see the TS120 as a preferred amp fir the NX Series. I have a TS120 non SE but I modded mine with Jupiter Silver bypass caps + all Gold Lion tubes. The caps took 100-200 hours to sound best but now it sounds absolutely lovely. Sound demos at my channel with NX-Otica's and Double Troubles.
Danny, I'm sure Thomas appreciates the review. And funny you should comment on transient decay because a long...long...time ago that was the immediate thing I noticed from between good and amazing amps...and speakers circa 1976-80. Thanks again Danny... I was fairly certain you would like Thomas's pieces... I've been bugging him to design an Integrated amp as well. Something around $1K. 20-25 Class A and say 65-75 Class A/B.
Thank you Danny for your review. What you said is the same as mine! I listened to these two amplifiers at an audio show, and I still didn’t believe that such a good sound performance could be achieved at this price. Then I thought it might be the problem with the songs. After a while, I went back to his room to listen again. OMG. The sound is very good. After that, my friends and I talked about this amplifier because my friends also make DIY amplifiers. They said that the cost of such an ultra-thick chassis and accessories would exceed $1000+ , If you add the labor and package, this amplifier for $1,500 is basically about the cost price, and there is basically no profit to be made. I really can’t understand how he did it, or is he really not asking for money and doing it for nothing?
That's an easy one, as far as high volume listening and the amp not doubling its wattage into 4 Ohms on the A75. There's plenty of power supply capacitance, but those tiny toroids can only muster up so much current after all. Personally, I feel that if someone wants to listen that loud, they should be at the 250 Watt + level amplifier. Your A75 is a really nice unit Thomas. Nice work!
Ain't no substitute for cubes , but I use Bryston B60 monoblocks with Klipsch Heresy , and I never feel the system is struggling or lacking for anything . I would probably pony up for a used Benchmark power amp rather than buy the A75 though
Thanks Danny. Even though we grew up blaring AC/DC, lots of us are in apartments now. For us, cranking it is no longer an option. An amp that handles moderate volumes with grace is an ideal product for us.
Nearfield subwoofing can help enormously as significantly less level is required (with the bonus of lessening the room's resonances). Or, for even greater tactile effect, and even less overall acoustic level, one of the many tactile transducer approaches would be ideal (enthusiasts with $50k systems are elevating their performance via $50 JBL subs utilized as tactile systems). Either platform, when you get closer to the sub, the perceived LF level and impact increases with no increase of contamination to your neighbors.
Danny, have Thomas send you his Galion TS A20. Its 20 watts of pure class A with high current delivery and excellent build quality. It's $3,750 but worth it. As you know, its about current delivery not watts especially when you have fairly efficient speakers.
First time viewer plus new subscriber ,,,…for me it was your body language that really drove your enthusiasm home for the TS 120 . I’m going to place an order ,…
This is the kind of review that I like. 10,000 words of flowery crap about equipment has little meaning, and I skip through much of that. This... I understand. 👍👍👍
I REALLY enjoyed and appreciate this review video. Sometimes it is hard select high dollar gear, but when someone like you, who I follow because I value your audiophile perspective, it helps me narrow down candidates and save me money. Keep up the great work, and keep sprinkling in the reviews. Review suggestion, Orchard Audio GaN amp. Thx!
The A75 seems to remove the veil between the vocalist and what they actually sound like. It’s remarkable. When I crank up the volume I get the exact opposite of what you’re describing… The music starts to get hard but never obnoxious. I prefer my Audio Research amp when driving it really loud levels. 95% of my the music that I listen to is acoustic jazz, blues, yacht rock, small group classical and a lot of other acoustic genres so I’m not experiencing the same issues that you are when you drive really hard. It does sound like more than 100 W per channel driving my Maggie 3.6 R’s
Bravo! I liked this video. I think you should do a few more like this. I have a tube amp, and the decay structure is something I enjoy about how it sounds. To me, it's more natural and organic than most solid state amps. How something sounds is the most important thing. You've established the credibility. Mix in a review like this once in a while.
Great review..Easier to interpret than many amp reviews from so called 'Amp experts ' as yours was more stripped down to the 'nuts and bolts' as it were..Review was "All killer and no filler" Well done to Thomas as well.
You mentioned AC/DC Bon Scott what a legend he never got the credit he deserved 1st time i heard his voice was from a big sound desighn boom box i was instantly blown away ! Brian Johnson done an amazing Job carring on the torture ' Thanks for the video '
Thanks for this offering. Some reviewers comment that the TS A 75 has a slightly tube sound. I’m not sure if that’s true. The second model seems to live up to the hype.
These days I don’t listen to my main system and instead have a good headphone set up however when Danny starts reccomending stuff you know it’s going to be good
Danny I really do respect your opinion on these things... don't be shy - keep it coming. I know you are an analogue guy but if you do have opinions on dacs and streamers I would like to hear it. They just keep getting better and better.
Really liked this video. Would request you to do a video educating us on some of the basics of component matching - voltage output from digital devices, acceptable voltage inputs on preamplifiers or integrated amplifiers, overall gain in the system and how all of that can impact the so called "synergy" of the system. I have noticed that a lot of us mix and match components from different manufacturers, but sometime the information is not available regarding the aspects mentioned above....
Great - but would be really interesting to have your thoughts on the TS A20, you indicate that the A75 doesn’t provide as good a harmonic decay as the TS120… so let’s see how the A20 does!
pretty tough to double current output as impedance drops in half unless really huge power trans and capacitor banks are used. The big Krells and Levinsons come to mind but they are much higher priced than this amp. Always impressive to see how much farther the dollar or pound goes when the dealer mark ups and dist mark ups are all removed from the cost structure equations.
There's plenty of capacitance. He went excessive on the capacitance as a matter of fact. It's totally dependent on the circuit topology and output devices chosen. Mosfets for example are voltage devices that do not double in current like bipolar transistors. Total myth
6:00 only amplifiers with massive power supply can double the wattage from 8 to 4 ohms, if this one goes from 75 to 100 it means that the transformer is not big enough to double, another thing is the quantity of output transistors, fewer transistors is easier to get excellent sound because of transistor matching, an amplifier with only 2 transistors sound more transparent than one with 4 transistors, but with less bass slam and damping factor, one of the best sounding amplifiers I have ever repaired is the Quad 303 that gives only 45 watts
Not true at all. In fact, it's definitely false with the given amplifier considering the size of transformer and the excessive capacitance he overspent on it. It boils down to the output devices. Most likely they are mosfets which do not always double in power because they are voltage devices rather than current like bipolar transistors. That's a gross oversimplification to say something should double in power and it's an audiophile wise tail that needs to disappear since it purely matters on the output devices and circuit topology.
@@HiFiWright You are wrong, the Ts-A75 use only 2 bipolar transistor on the output to achieve more transparency, possibly 2SA1295 and 2SC3264, a lot of capacitance but a couple of only two 200 watt transformers, the sum of small transformers and 1 positive transistor and 1 negative transistor per channel avoid the possibility of doubling the power at 4 ohms, the designer preferred transparency over power but to give punch in the bass use many capacitors, thanks for reading
I believe Thomas said it doesn’t double mainly for reliability reasons. The design was limited to keep it from running at max and possibly burning out components.
@@Pok-001 You need a current limiting circuit to do that, but it will affect the sound, no amp can double power only using 2 transistors, no need to mention that the transformer should be a 300 watt instead of 200 watt in order to produce 150 watts at 4 ohms, the transformer should be bigger in watts than the power you desire to get from it
@@ThresholdZhor you’re correct about the transformer should have some reserves/headroom when amp is maxed. Does it have one pair of transistors? Maybe that’s why it’s limited? So it preserves sound quality? Limiting power at the power stage would keep transistors (depending on their values) running more efficiently/cooler. Which would only improve SQ. If it’s running one pair of transistors and just enough power transformers maybe that was a decision to keep it at the price point? Regardless sounds like it would have plenty juice for most. Especially considering type of speakers most people would have at this price point.
This is cool! I got one of these from Thomas about 5 months ago l ❤ it!! I liked the tubes that I ordered with it, but bought some Mullard power tubes, that sound much better to me!
Nothing wrong with that review. Got my system pretty much where I want myself but if I was looking I'd definitely consider Galion. Nice work. By the way, if you ever went about doing a tuning kit for b&w 801n's I'm all ears!
A lot of audiophiles seek out a "warm" sound in their amps. But as old man Carver demonstrated, "warm" is not accurate. It's "warm" due to distortion. Carver showed that you can add distortion for that warm sound. Not only could you add distortion, but he designed an amp to add that distortion. So he knew exactly what distortion to add to a solid state amp and how to do it. I'm of the audiophile school of total control over the sound. If I want it to sound "warm", I can add that in. If I want it to sound "weird", then I can add that in too. But if I want it to sound exactly as the audio engineer meant it to sound, I have to start with equipment that is as accurate as possible. An amp that starts out sounding "warm", cannot sound accurate. And that's my criticism. With the right equipment, you can make an accurate signal sound warm. But you cannot make a warm signal sound accurate. It's like your cup of coffee. You can add sugar, you can add cream, you can add mustard if that's what you want. But you can't remove it once it's in there. 99% of all amps need at least one of two things - a better power supply, and internal EM shielding.
It seems like he knows what he doing in speakers and amps drive speakers so what he says has to be relevant. There is so little content on TH-cam about the technical challenges of designing and building a pair of speakers that Danny’s videos help me think through some of the things I will need to consider when taking on my own DIY Speaker project exscially since the cost quickly approaches $1000.00
Harmonic decay structure..........;reserved for the better amplifiers .....when the notes live their life until the end . One does not know what this is before one heard it . Even a lot of very impressive sounding and expensive amplifiers are missing THIS QUALITY..... This is / was also an issue with many digital sources.......the difference in perception and the connection to the music when reproduced correctly ( with this quality ) is huge !
Dan , you hit the nail right on the head. The A-75 is a very good amp for the money , but there just isn't sufficient power for peaks and transients making the music sound compressed. You don't call yourself an amp specialist , but you actually are.
That's not what Danny Said ' I bet you don't even own a TS-A75 ' My buddy 'Stereo Review' Measured my Triangle speakers down to 2.5 ohms @132hz and TS-A75 drives the hell out of them in a room 14ft x 22ft here's the proof ' th-cam.com/users/shortst6Mg-qB3dE4?si=8XEnKZ-ktsUgU0a0
I don't think that is what Danny said. As long as he did not push it to crazy volume, the amp can even rival his own reference gear, which means there should be no problem with transients and peaks. Danny, correct me if I am wrong.
They don't really do reviews over there. They just take measurements and theorize how things sound. It is also a pretty toxic environment over there. They get hostel if someone starts talking about how things sound.
One thing every audiophile should know. Measurements mean jack! They give you numbers. That’s it. I’ve heard many pieces of gear that “measured great” and sounded like trash.
I build my own amplifiers. Based on tube amplifiers audio reproduction. Build my own speakers as well. Some of the crossovers cost more than some whole speaker products. Way more. My last pair I built are mostly Bowers & Wilkins products that I hated them. But yes I can do good stuff with them.
I've been interested in the Vincent Audio SV-237MKII integrated and Jay has done a review on it, would be cool if Danny heard it on his system to see what he thought about it.
Nice change fom the norm. Pls do more review videos... But ONLY if its outstanding and up to ur standard as we have more than enough normal review videos in youtube.
Personally, i liked how you once made a reference to how you design your speakers to work best with all types of amp design... (tho all amps can be upgtraded to improve the sound of a good speaker design, at a cost & to perdonal taste) ...but its good to hear reviews particularly like this, i.e. of amps that have shocked you particulsrly for their humble.. (for the sound quality on offer) ..price . i.m.o.
Is it desirable for power to double with impedance? We generally want linearity in amps. Does impedance-dependent power output introduce a big variable in speaker matching as impedance varies by frequency in all speakers?
A lot of use-to-be TH-cam personalities are now going into the audio industry business. A new medium helps where as print and show coverage cost much more. I wish him well, but at some point who will police the police. Thank you for your honest option.
It would be interesting to compare these amps with some of the clone/copy amplifiers that you can buy from China.I own a few of them and believe they give amazing sound .Not just for the money but by any standards.The FM Acoustic FM300A copies for example sound extremely good .As does the FM Acoustics FM155 preamp which you can get for about $300 .That is better than most of the $5000 preamps I have heard.The real things would cost you around $50,000!The days of needing to spend $5000 or more to get a good sounding amplifier are gone.Which is great because we can spend more of our budget on speakers and room treatment which is where you are going to gain the most benefit.
A couple of things worth mentioning: it had been a while since I used this amp. I brought it to Danny's, and we started listening right away. While the amp was warmed up by the time we got to AC/DC, we hadn't bothered checking the bias. When it sounded off, I pressed the change button on the amp, which shows whether or not the power tubes need biasing, and all four of them did. So, at that moment, I just pressed the bias button, and we got back to listening. Danny is right, though; it definitely sounded better.
Please continue the amp reviews... 'No B S" reviews are tough to find on TH-cam...when a reviewer accepts money for a review, I don't know if they can be totally unbiased. Yes, they all say ' Everything I'm about to say is my opinion alone'. Sorry, I have become very skeptical in my latter years. Ok off the soap box...Love what you are doing at GR-Research...keep the great content coming...
I hear a lot here abput "liking the sound." Are there amps that don't add or subtract or change anything about the sound going into them? Can we just make the sound louder without changing it otherwise?
Hey Danny, thanks for bringing this out. Glad to hear that you found awesome sounding amps, i think both of these Galions are amazing as well. Did they work equally well on the speakers you tried, could they both drive most speakers well at reasonable volumes?
Very nice you did this, Thomas is making amazing stuff, and he does it from the heart.
Really, really enjoyed this one, Danny. It's actually refreshing to hear your take on electronics. I hope you do consider doing more of these!
I purchased a TS120se about a year and a half ago. Love the sound of it after some break in time. Always thought my speakers weren't quit up to the task.

That speaker only goes down to 70hz. What subwoofer do you use? 🙏
What do you think is the best type of speaker pairing for this amp?
I love to see Danny do this type of videos. PLZ do MORE!!!

Wow, the timing of your comment is uncanny.
That's good that you are picky, I wish you did more amp reviews .
On products that are non unobtainium; affordability is a very subjective factor.
@@fonkenful yes I agree,
Thanks Danny, I like hearing your recommendations even if it's just pretty quick.

Running the TS A75 with Buchardt S400 MkII in a small-ish room and the amp makes these speakers sparkle!
This was refreshing. I'd definitely like to see more equipment reviews. Thanks for keeping things interesting, Danny!

Most likely they are mosfets which do not always double in power because they are voltage devices rather than current like bipolar transistors. That's a gross oversimplification to say something should double in power and it's an audiophile wise tail that needs to disappear since it purely matters on the output devices and circuit topology.
@@HiFiWright You are wrong, the Ts-A75 use only 2 bipolar transistor on the output to achieve more transparency, possibly 2SA1295 and 2SC3264, a lot of capacitance but a couple of only two 200 watt transformers, the sum of small transformers and 1 positive transistor and 1 negative transistor per channel avoid the possibility of doubling the power at 4 ohms, the designer preferred transparency over power but to give punch in the bass use many capacitors, thanks for reading
I believe Thomas said it doesn’t double mainly for reliability reasons. The design was limited to keep it from running at max and possibly burning out components.
@@Pok-001 You need a current limiting circuit to do that, but it will affect the sound, no amp can double power only using 2 transistors, no need to mention that the transformer should be a 300 watt instead of 200 watt in order to produce 150 watts at 4 ohms, the transformer should be bigger in watts than the power you desire to get from it
@@ThresholdZhor you’re correct about the transformer should have some reserves/headroom when amp is maxed.
Does it have one pair of transistors? Maybe that’s why it’s limited? So it preserves sound quality?
Limiting power at the power stage would keep transistors (depending on their values) running more efficiently/cooler. Which would only improve SQ.
If it’s running one pair of transistors and just enough power transformers maybe that was a decision to keep it at the price point? Regardless sounds like it would have plenty juice for most. Especially considering type of speakers most people would have at this price point.
I'm still working my old GAS Ampzilla. It still sounds great at about 45 yrs old.
Hoping they go through amps thats available in the market and share the ones with synergies with their speakers. From budget, DIY to high end.
Im liking the emotiva differential equipment
I really enjoyed this video, Danny. Thank you.
This is cool! I got one of these from Thomas about 5 months ago l ❤ it!! I liked the tubes that I ordered with it, but bought some Mullard power tubes, that sound much better to me!
I wish more reviewers were more like that , no sugarcoating , and more picking .
Curious to hear what you would think of Galion's new amps: Galion A20 class A SS amp ($3750) and TS34 (EL34 tube $3000)!
Please keep reviewing amps! Preamps and DACs too! Would especially be interested in your opinion of relay ladder vs chip-based DACs. Thank you kindly.
Nothing wrong with that review. Got my system pretty much where I want myself but if I was looking I'd definitely consider Galion. Nice work. By the way, if you ever went about doing a tuning kit for b&w 801n's I'm all ears!
$1,500 is on the edge of my budget. I don't jam much these days and sound quality is more important than volume.
I agree. Theres always a compromise for what we are willing to spend. A higher current amp would have likely resulted in a more expensive amp.
great honest review.
I've owned the Galion since it first came out and it if tremendously hard to say a bad thing!😊
A lot of audiophiles seek out a "warm" sound in their amps. But as old man Carver demonstrated, "warm" is not accurate. It's "warm" due to distortion. Carver showed that you can add distortion for that warm sound. Not only could you add distortion, but he designed an amp to add that distortion. So he knew exactly what distortion to add to a solid state amp and how to do it.
I'm of the audiophile school of total control over the sound. If I want it to sound "warm", I can add that in. If I want it to sound "weird", then I can add that in too. But if I want it to sound exactly as the audio engineer meant it to sound, I have to start with equipment that is as accurate as possible. An amp that starts out sounding "warm", cannot sound accurate. And that's my criticism. With the right equipment, you can make an accurate signal sound warm. But you cannot make a warm signal sound accurate.
It's like your cup of coffee. You can add sugar, you can add cream, you can add mustard if that's what you want. But you can't remove it once it's in there.
99% of all amps need at least one of two things - a better power supply, and internal EM shielding.
You pretty much nailed it. That’s why we call it ‘high fidelity’ ain’t it?
Can the TS A75 be bridged into a Mono configuration?
No
It seems like he knows what he doing in speakers and amps drive speakers so what he says has to be relevant. There is so little content on TH-cam about the technical challenges of designing and building a pair of speakers that Danny’s videos help me think through some of the things I will need to consider when taking on my own DIY Speaker project exscially since the cost quickly approaches $1000.00
Hello Danny I would like to hear your opinion on rel subwoofer do you think their worth it how they made and how they sound Thank You Michel
I can tell you that quite a few REL sub owners have upgraded them to our servo controlled subs.
Thank You I'll check that out
I love all your stuff!!
Yes more of these!
Harmonic decay structure..........;reserved for the better amplifiers .....when the notes live their life until the end .
One does not know what this is before one heard it .
Even a lot of very impressive sounding and expensive amplifiers are missing THIS QUALITY.....
This is / was also an issue with many digital sources.......the difference in perception and the connection to the music when reproduced correctly ( with this quality ) is huge !
Dan , you hit the nail right on the head. The A-75 is a very good amp for the money , but there just isn't sufficient power for peaks and transients making the music sound compressed. You don't call yourself an amp specialist , but you actually are.
That's not what Danny Said ' I bet you don't even own a TS-A75 ' My buddy 'Stereo Review' Measured my Triangle speakers down to 2.5 ohms @132hz and TS-A75 drives the hell out of them in a room 14ft x 22ft here's the proof '
th-cam.com/users/shortst6Mg-qB3dE4?si=8XEnKZ-ktsUgU0a0
I don't think that is what Danny said. As long as he did not push it to crazy volume, the amp can even rival his own reference gear, which means there should be no problem with transients and peaks. Danny, correct me if I am wrong.
I spend lots of time over at ASR reading reviews and looking at measurements. be interesting to see these put to tests:}
They don't really do reviews over there. They just take measurements and theorize how things sound. It is also a pretty toxic environment over there. They get hostel if someone starts talking about how things sound.
One thing every audiophile should know. Measurements mean jack! They give you numbers. That’s it. I’ve heard many pieces of gear that “measured great” and sounded like trash.
@@FidelitySoundzas Danny said in this review, measurements correlate to the sound. You may not like it but numbers don’t lie.
No mention of speaker sensitivity/impedance? Does that factor into decay structure at high output levels?
How would you compare that Gallion 75 to Yamaha AS2100 or Marantz 8006?
He doesn't have a clue.
Danny, thanks for the amplifier recommendations. Have you ever listened to any of the Bob Carver tube amps?
I build my own amplifiers. Based on tube amplifiers audio reproduction. Build my own speakers as well. Some of the crossovers cost more than some whole speaker products. Way more. My last pair I built are mostly Bowers & Wilkins products that I hated them. But yes I can do good stuff with them.
On jour Robert quel condensateurs préférez vous utiliser dans vos montages
Been looking for an upgrade from a pair of Amp Camp Amps … A75 was on my list, now it’s leading.
Thanks for this video. Although pricey, might be worth the investment.
I've been interested in the Vincent Audio SV-237MKII integrated and Jay has done a review on it, would be cool if Danny heard it on his system to see what he thought about it.
British Audiophile also reviewed it.
th-cam.com/video/nuJu2uG5BKY/w-d-xo.htmlsi=i21gsNGcmFOZzwLz
Nice change fom the norm. Pls do more review videos... But ONLY if its outstanding and up to ur standard as we have more than enough normal review videos in youtube.
Personally, i liked how you once made a reference to how you design your speakers to work best with all types of amp design... (tho all amps can be upgtraded to improve the sound of a good speaker design, at a cost & to perdonal taste) ...but its good to hear reviews particularly like this, i.e. of amps that have shocked you particulsrly for their humble.. (for the sound quality on offer) ..price .
i.m.o.
So there is the TS A20 waiting in the queue.
Yes' do more reviews like this
Thanks for this!
Curious to know what preamp was used with amp
I was using a Dodd Audio battery powered tube pre-amp.
Nice job 👍
Is it desirable for power to double with impedance? We generally want linearity in amps. Does impedance-dependent power output introduce a big variable in speaker matching as impedance varies by frequency in all speakers?
A lot of use-to-be TH-cam personalities are now going into the audio industry business. A new medium helps where as print and show coverage cost much more. I wish him well, but at some point who will police the police. Thank you for your honest option.
Nice review.
It would be interesting to compare these amps with some of the clone/copy amplifiers that you can buy from China.I own a few of them and believe they give amazing sound .Not just for the money but by any standards.The FM Acoustic FM300A copies for example sound extremely good .As does the FM Acoustics FM155 preamp which you can get for about $300 .That is better than most of the $5000 preamps I have heard.The real things would cost you around $50,000!The days of needing to spend $5000 or more to get a good sounding amplifier are gone.Which is great because we can spend more of our budget on speakers and room treatment which is where you are going to gain the most benefit.
Thomas needs to add a tube amp only to the line up.
what was used as pre amp and source?
what did Ron "do"?
My suspiction: other tubes
A couple of things worth mentioning: it had been a while since I used this amp. I brought it to Danny's, and we started listening right away. While the amp was warmed up by the time we got to AC/DC, we hadn't bothered checking the bias. When it sounded off, I pressed the change button on the amp, which shows whether or not the power tubes need biasing, and all four of them did. So, at that moment, I just pressed the bias button, and we got back to listening. Danny is right, though; it definitely sounded better.
Please continue the amp reviews... 'No B S" reviews are tough to find on TH-cam...when a reviewer accepts money for a review, I don't know if they can be totally unbiased. Yes, they all say ' Everything I'm about to say is my opinion alone'. Sorry, I have become very skeptical in my latter years. Ok off the soap box...Love what you are doing at GR-Research...keep the great content coming...
Will you get the A20 class A for review from Gallion?
I hear a lot here abput "liking the sound." Are there amps that don't add or subtract or change anything about the sound going into them? Can we just make the sound louder without changing it otherwise?
There is a lot more to it than that.
Curious if this can drive LRS capably
Hey Danny, thanks for bringing this out. Glad to hear that you found awesome sounding amps, i think both of these Galions are amazing as well. Did they work equally well on the speakers you tried, could they both drive most speakers well at reasonable volumes?
Have you ever listen to Decware Tube Amps?
I have the Galion TS 120 fir review. Its the best amp I have heard to date
I also love the TS120, its a phenomenal amp.
@@Newrecordday2013 is there any value in using a separate preamp ? or just use it as an integrated and put that $ elsewhere?
