My Long List of Amplifiers and My Personal Review of Each!


So I have been in a long journey looking to find the best amplifiers for my martin logan montis. As you know, the match between an amplifier and speakers has to be a good "marriage" and needs to be blend exquisitely. Right now, I think I might have found the best sounding amplifier for martin logan. I have gone through approximately 34-36 amplifiers in the past 12 months. Some of these are:

Bryston ST, SST, SST2 series
NAD M25
PARASOUND HALO
PARASOUND CLASSIC
KRELL TAS
KRELL KAV 500
KRELL CHORUS
ROTEL RMB 1095
CLASSE CT 5300
CLASSE CA 2200
CLASSE CA 5200
MCINTOSH MC 205
CARY AUDIO CINEMA 7
OUTLAW AUDIO 755
LEXICON RX7
PASS LABS XA 30.8
BUTLER AUDIO 5150
ATI SIGNATURE SERIES 6005

With all that said, the amplifiers I mentioned above are the ones that in my opinion are worth mentioning. To make a long story short, there is NO 5 CHANNEL POWER AMP that sounds as good as a 3ch and 2ch amplifier combination. i have done both experiments and the truth is that YOU DO lose details and more channel separation,etc when you select a 5 channel power amplifier of any manufacturer.
My recollection of what each amp sounded like is as follows:

ATI SIGNATURE SERIES 6005 (great power and amazing soundstage. Very low noise floor, BUT this amplifiers NEEDS TO BE cranked up in order to fully enjoy it. If you like listening at low volume levels or somewhat moderate, you are wasting your time here. This amp won’t sound any different than many other brands out there at this volume. The bass is great, good highs although they are a bit bright for my taste)

NAD M25 (very smooth, powerful, but somewhat thin sounding as far as bass goes)
Bryston sst2(detailed, good soundstage, good power, but can be a little forward with certain speakers which could make them ear fatiguing at loud volumes)

Krell (fast sounding, nice bass attack, nice highs, but some detail does get lost with certain speakers)

rotel (good amp for the money, but too bright in my opinion)

cary audio (good sound overall, very musical, but it didn’t have enough oomph)

parasound halo (good detail, great bass, but it still holds back some background detail that i can hear in others)

lexicon (very laid back and smooth. huge power, but if you like more detail or crisper highs, this amp will disappoint you)

McIntosh mc205 (probably the worst multichannel amp given its price point. it was too thin sounding, had detail but lacked bass.

butler audio (good amplifier. very warm and smooth sweet sounding. i think for the money, this is a better amp than the parasound a51)

pass labs (very VERY musical with excellent bass control. You can listen to this for hours and hours without getting ear fatigue. however, it DOES NOT do well in home theater applications if all you have is a 2 channel set up for movies. The midrange gets somewhat "muddy" or very weak sounding that you find yourself trying to turn it up.

classe audio (best amplifier for multi channel applications. i simply COULDNT FIND a better multi channel amplifier PERIOD. IT has amazing smoothness, amazing power and good bass control although i would say krell has much better bass control)

Update: The reviews above were done in January 2015. Below is my newest update as of October 2016:



PS AUDIO BHK 300 MONOBLOCKS: Amazing amps. Tons of detail and really amazing midrange. the bass is amazing too, but the one thing i will say is that those of you with speakers efficiency of 87db and below you will not have all the "loudness" that you may want from time to time. These amps go into protection mode when using a speaker such as the Salon, but only at very loud levels. Maybe 97db and above. If you don’t listen to extreme crazy levels, these amps will please you in every way.

Plinius Odeon 7 channel amp: This is THE BEST multichannel amp i have ever owned. Far , but FAR SUPERIOR to any other multichannel amp i have owned. In my opinion it destroyed all of the multichannel amps i mentioned above and below. The Odeon is an amp that is in a different tier group and it is in a league of its own. Amazing bass, treble and it made my center channel sound more articulate than ever before. The voices where never scrambled with the action scenes. It just separated everything very nicely.

Theta Dreadnaught D: Good detailed amp. Looks very elegant, has a pleasant sound, but i found it a tad too bright for my taste. I thought it was also somewhat "thin" sounding lacking body to the music. could be that it is because it is class d?

Krell Duo 300: Good amp. Nice and detailed with enough power to handle most speakers out there. I found that it does have a very nice "3d" sound through my electrostatics. Nothing to fault here on this amp.
Mark Levinson 532H: Great 2 channel amp. Lots of detail, amazing midrange which is what Mark Levinson is known for. It sounds very holographic and will please those of you looking for more detail and a better midrange. As far as bass, it is there, but it is not going to give you the slam of a pass labs 350.5 or JC1s for example. It is great for those that appreciate classical music, instrumental, etc, but not those of you who love tons of deep bass.

 It is articulate sounding too
Krell 7200: Plenty of detail and enough power for most people. i found that my rear speakers contained more information after installed this amp. One thing that i hated is that you must use xlr cables with this amp or else you lose most of its sound performance when using RCA’s.

Krell 402e: Great amp. Very powerful and will handle any speaker you wish. Power is incredible and with great detail. That said, i didn’t get all the bass that most reviewers mentioned. I thought it was "ok" in regards to bass. It was there, but it didn’t slam me to my listening chair.

Bryston 4B3: Good amp with a complete sound. I think this amp is more laid back than the SST2 version. I think those of you who found the SST2 version of this amp a little too forward with your speakers will definitely benefit from this amp’s warmth. Bryston has gone towards the "warm" side in my opinion with their new SST3 series. As always, they are built like tanks. I wouldn’t call this amp tube-like, but rather closer to what the classe audio delta 2 series sound like which is on the warm side of things.

Parasound JC1s: Good powerful amps. Amazing low end punch (far superior bass than the 402e). This amp is the amp that i consider complete from top to bottom in regards to sound. Nothing is lacking other than perhaps a nicer chassis. Parasound needs to rework their external appearance when they introduce new amps. This amp would sell much more if it had a revised external appearance because the sound is a great bang for the money. It made my 800 Nautilus scream and slam. Again, amazing low end punch.

Simaudio W7: Good detailed amp. This amp reminds me a lot of the Mark Levinson 532h. Great detail and very articulate. I think this amp will go well with bookshelves that are ported in order to compensate for what it lacks when it comes to the bass. That doesn’t mean it has no bass, but when it is no Parasound JC1 either.
Pass labs 350.5: Wow, where do i begin? maybe my first time around with the xa30.8 wasn’t as special as it was with this monster 350.5. It is just SPECTACULAR sounding with my electrostatics. The bass was THE BEST BASS i have ever heard from ANY amp period. The only amp that comes close would be the jC1s. It made me check my settings to make sure the bass was not boosted and kept making my jaw drop each time i heard it. It totally destroyed the krell 402e in every regard. The krell sounded too "flat" when compared to this amp. This amp had amazing mirange with great detail up top. In my opinion, this amp is the best bang for the money. i loved this amp so much that i ended up buying the amp that follows below.

Pass labs 250.8: What can i say here. This is THE BEST STEREO AMP i have ever heard. This amp destroys all the amps i have listed above today to include the pass labs 350.5. It is a refined 350.5 amp. It has more 3d sound which is something the 350.5 lacked. It has a level of detail that i really have never experienced before and the bass was amazing as well. I really thought it was the most complete power amplifier i have ever heard HANDS DOWN. To me, this is a benchmark of an amplifier. This is the amp that others should be judged by. NOTHING is lacking and right now it is the #1 amplifier that i have ever owned.

My current amps are Mcintosh MC601s: i decided to give these 601s a try and they don’t disappoint. They have great detail, HUGE soundstage, MASSIVE power and great midrange/highs. The bass is great, but it is no pass labs 250.8 or 350.5. As far as looks, these are the best looking amps i have ever owned. No contest there. i gotta be honest with you all, i never bought mcintosh monos before because i wasn’t really "wowed" by the mc452, but it could have been also because at that time i was using a processor as a preamp which i no longer do. Today, i own the Mcintosh C1100 2 chassis tube preamp which sounds unbelievable. All the amps i just described above have been amps that i auditioned with the C1100 as a preamp. The MC601s sound great without a doubt, but i will say that if you are looking for THE BEST sound for the money, these would not be it. However, Mcintosh remains UNMATCHED when it comes to looks and also resale value. Every other amp above depreciates much faster than Mcintosh.

That said, my future purchase (when i can find a steal of a deal) will be the Pass labs 350.8. I am tempted to make a preliminary statement which is that i feel this amp could be THE BEST stereo amp under 30k dollars. Again, i will be able to say more and confirm once i own it. I hope this update can help you all in your buying decisions!

Yes, I believe we all remember your thoughts on 'certain footers'.....wasn't it around that time that you were banned from WBF?  Hmmm

Interesting...hmmm. .. I’ll have to ask him next time I speak to him. You all know how I feel about footers...

or certain footers...

@keithr 

Do you own those footers?

Yes, and there was a huge WBF thread where I called him out on that review.

He says the below in his PF review of the footers - not sure if that's what keithr meant?  Or, perhaps a different quote?

"It was as if my linestage, mono amps, and sources, even my loudspeakers, had all been replaced by components that were at least two to three times more expensive!"

Dave

You should ask Greg why he think CS footers are more important than speaker upgrades

I enjoyed Part 1 video with Greg Weaver.

 

Happy Listening!

Thank you everyone. More is coming and the next 2 parts will have a lot of the questions you've been waiting to get answers for.

Great to listen to this old school gentleman. 50 years brings with it a wealth of knowledge and wisdom. Greg Sounds like a guy who genuinely loves music and has a gift in his ability to listen and articulate what he is hearing. He has seen so much over the years the advances as well as some of the decline in audio design. Thanks to Greg for sharing and come on to talk to us. Thank you Jay for having him.  Would be nice to know his system as well. 

Thanks Jay for bringing in Greg...what a cool guy with a wealth of knowledge.  It was refreshing to hear him speak of print and written articles / reviews and how important he thinks YouTube has become to compliment the writing he does.  Funny to hear him talk about reviewers that have little to no experience giving a product their highest recommendation when they have not heard similar products in the same price range or don't have the equipment to properly evaluate the gear. Same thing you've been preaching for years.   Looking forward to part two.

Ok folks,

Let's open up a discussion here about the first video. What are your early thoughts about the points he made?

 

I have received many messages from people wanting for me to release the video above. I have moved up the time to 11AM E.T. time today. I hope you all enjoy this Part 1 of 3. I urge  you to relax, watch it in its entirety and hear from one of the most well-known reviewers today. This is NOT the video for you to skip through to locate answers. He took the time to open up and I believe It is important that we all listen to what he has to say. Again, this is part 1 of 3 so it should be clear that he won't be answering all questions on this particular video. 

Enjoy !

Folks, 

You are hearing it here first: I have just finished an interview with Greg Weaver. In case you do not know who he is, Greg has been reviewing equipment for the following publications:

  1. The Absolute Sound
  2. Soundstage
  3. Stereo Times
  4. Positive Feedback
  5. TONEAudio

During this 90 minute interview (which will be broken out in 3 parts), I had the opportunity to ask an Audio Reviewer with over 40 years of experience questions that have never been answered before by a high-profile audio reviewer, but I was fortunate enough to ask. Here are a few of the questions I asked:

  1. Why don't we ever see bad reviews published?
  2. Should print publications have dedicated YouTube channels?
  3. What does it take for a new brand to be reviewed by a magazine?
  4.  How has the landscape changed for reviewers?
  5. How long does a reviewer live with a product before it is reviewed?
  6. What is the most important component in a system?
  7. Do reviewers evaluate components with their stock powercords?
  8. Should we re-position our speakers when we change a component?
  9. Do you consider system synergy when evaluating components?
  10. How should funds be allocated in a system?

You guys DO NOT want to miss this. I promise you, there is A LOT of great information and I am the FIRST CHANNEL to interview a well-known reviewer that has been doing this longer than I have been alive. More amazing things coming your way SOON!!

 

Jay

 

@viber6

The entire speaker is very coherent, but also more accurate.  The issue is with accuracy comes "THE TRUTH" and sometimes the truth isn't the easiest thing to accept. 

 

Jay,

Aside from bass, how does the S7 midrange/HF compare with your Focal?  Normally, if bass is accurate, so is the rest of the range.  

Hope everyone has a nice holiday with some music as well.

Really enjoying the latest content Jay. I am a sealed box devotee.

Thanks for all the work and thank you for your service.

The room - the most overlooked component in an audio system. One variable that is so specific to our audio adventure. 

You are so right Jay finding the right speaker for YOUR ROOM is the key. I recently purchased the new pair Wilson Alexx Vs and tho my electronics are subpar for this speaker, they sound absolutely fantastic. They must of just coupled perfectly in my room. If I’m home they are playing continuously. I Love them, best speaker I’ve ever heard in my room. They just sound right. So glad you found the one for your room, isn’t it great to finally find the right one?  Good luck on you’re continuing journey it’s been enlightening and very entertaining for me. Thank you. 

In my room, no Wilson speaker went as deep as my S7 Magico.

I’ve said it before, to get most out of a ported speaker design, speaker placement is KEY. It is painful at times to find the perfect spot with ported speakers. It’s not easy get a balanced presentation where the bass doesn’t overpower the mids or highs and sometimes you gotta be willing to change your listening position if moving the speakers isn’t doing the magic.

That said, yes ported speakers hit deep DEEP, but they don’t exactly articulate bass frequencies as sealed cabinets do although I'm not saying they don't articulate bass frequencies. 

I think the bigger factor here is THE ROOM. Finding the right speaker design for your room is KEY. 

Actually, all things being equal, a sealed design will go deeper (12db vs.24 db roll-off on ported). 

@charyo,

I agree with you to some extent, however we are talking about two completely different speaker designs.  The Wilson XLF @ 655lbs with (1) 15" and (1) 13" woofers and using its port to extend the bass should theoretically produce more, deeper bass than the Magico S7 @ 300lbs with (3) 10" woofers in a sealed cabinet with no help from a port and with less interaction from the room.  I have had many ported and sealed cabinet speakers.  It has been my experience that a larger ported design will produce more, deeper bass and also interact with the room more as opposed to a sealed cabinet design which I found to produce faster tighter bass and interact less with the room, but not produce more, deeper bass. 

 
Jay has reported the S7's to have the best, deepest, tightest bass he has had in his room.  That is why I said Alon Wolf should be commended for his design.

@rbach - I have always found that bass response is the product of the speaker/room relationship more than the size.  In my room, I have had small standmounts produce a better, fuller bass response than larger floorstanders.  It's just the way the speaker interfaces with the room. IMO.

Jay, your system has gone to a completely different level. Before, you could always easily tell you were listening to a microphone recording of a system playing. It is sounding so good now, this is no longer clear. Two thumbs way up.

 

I find it fascinating that with all of the speakers Jay has owned, the Magico S7 has the best bass he’s heard in his room. Hard to believe that a medium size speaker beats those huge Wilsons. Alon Wolf should be commended for such a wonderful design.

Yes you are right very expensive to repair. Especially Mágico $$$$$. No slack with that company. 

From Tidal (HIFI Quality) can’t get Master Audio on this one.

DEEP BASS speaker test. This is probably the deepest Bass that I have heard 

I would like to hear thoughts about this one. Crank it up & it will shake your room.

 

 

Magico S7 is 300 lbs...front heavy...you can’t lift it alone or you’ll find yourself in the same position as the idiot who did exactly that and the speaker fell forward while he attempted to stop it from falling on the ground so he stuck his hand and it broke his arm plus the speaker was destroyed. You can’t fool around with this type of gear. Everything is expensive to repair.

Impressive sound, but no meaningful statements can be made.  Too many variables, the recording being the largest unknown.  If you present the Focal speakers with the same components and recording, then a proper assessment can be made.  You know the best positions for each speaker, and neither speaker is too heavy, so you can do the swap in little time.

Thanks everyone for the comments above. I understand I’m not really appealing to everyone but how doesn’t someone do that?

The big channels certainly don’t appeal to the ultra high end either so many folks won’t watch reviews on 599 dollar bookshelf speakers. I think it’s important to identify what floats your boat but not be close minded. I think I’ve had flexibility by adding brands like tekton, Martin Logan, Amazon prime cables and the krell integrated which i haven’t reviewed yet.

I can’t afford a 2000HP Calvo Dodge Viper but I LOVE WATCHING videos about that monster.

Some people don’t want to watch or follow things they can’t afford and others simply enjoy watching and touching things they may never be able to afford. That said, we are all different and i respect that 100%.

Folks, pretty soon I’ll do a comparison of QOBUZ VS Tidal. I need to find songs that can show the differences and let you all hear these.

Lastly, this weekend I’ll host a private LIVESTREAM for those who want to donate to the channel. The purpose of this is to talk about products that i have never showcased on my channel or talked about openly plus answer questions. I will have no more than 25 seats available for this in order to dedicate my attention to those folks who want to be part of this experience. If you are interested in being part of this, send me a private message. The link will be sent via email and the livestream will not be available after it ends.

Thanks for the support!

@willgolf 

And then there's folks like me who have crazy curiosity and love and enjoy what WC is doing.  Even though I am no longer into two channel (HT only now), I'm still here.  I also like watching videos of Porsche vs Corvettes and other cars too.  I guess I'm a curious comparison type of guy.

Dave

I have followed WC's / Jay's Audiolab from the beginning.  It has been a source of information for me.  Jay has worked hard and has a definitive path he wants to take and that is cool.  However, for me and I would imagine most who follow Jay are not in his price league.  Consequently, it does not have the same panache it once had.  I choose not to afford the components Jay now tests.  Therefore it is not as relevant for ME.  I wish there was a Jay Jr who would do the same thing with mid-level equipment.

This in no way shape or form is a criticism. It is just my opinion of the relevance for ME.  I still check it out from time to time and I would say Jay has a set of brass balls to do what he does.  To that, I say enjoy your journey Jay and thanks!

 

I've seen many listeners make such a comparison and the vast majority of them find Qobuz to easily beat Tidal based purely on their sound quality.

@thezaks +1

Yes Jay, I am also interested in the differences you could hear between the two services.  Great idea.
