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!

I try to assemble a system that recreates the illusion of a live performance. Earlier in this thread, I became aware this isn't everyone's goal. Whitecamaross and many contributors stated their own preferences - and that's fine, our systems allow us to enjoy our music the way we want.
Occasionally, I gain great value and insight from whitecamaross and others sharing their experiences. This just happened, which prompted me to contribute.
There are many variables involved when striving to recreate the illusion of a live performance - the listening room acoustics and the quality of the recording are 2 examples.
There are times though when equipment unquestionably presents things more realistically (like when applause is imaged very clearly and distinctly as being in front of the performance instead of being background haze).
A system like this conveys music precisely as it was performed and recorded. Software (the recording) becomes critical. Most rock music is no longer engaging when replayed on our stereo, we prefer to listen to well recorded acoustic performances; contemporary jazz, solo artists with bands and orchestra music too - again, all recorded well that allows one to experience the venue in which the performance occurred.
While others may enjoy equipment that allows music that isn't recorded as well to be portrayed in a more enjoyable way (sweetness per whitecamaross), we prefer our system to have the highest fidelity possible - because when great performances (that are recorded very well) are listened to, they're an exceptional experience.
Recently, whitecamaross described what I experienced with Wilson speakers - they convey different acoustics of equipment / performance / recording / venue very well. And kstaken very well compared the Luxman and Benchmark equipment. I've always wondered what the Luxman sounded like and now, with this comparison - I have a good insight (minus the expense of the experience). And I have the insight with the Benchmark equipment as well so thank you kstaken!
Humbly, I would also like to share a few of my own requests and findings.
First - whenever we're evaluating something, our system must be at a performance level that will easily and clearly allow the change to heard / noticed / observed. Yes, whitecamaross's system is that and more, but it's amazing how many people state cables make no difference. Everyone who listened to our system easily identified the different sound (when cables were switched blindly) and which way sounded more realistic.
Second - when we make a change, it should be only with a single component in a system, and with music we're intimately familiar with (and again with well recorded music). This way, we can specifically identify what difference that change made. Sometimes whitecamaross makes multiple changes that makes acutely identifying a components' sound more difficult (and I realize this is done to obtain a desired result).
Finally - I compared Pass XA-200.5 with the Momentum monos in a system I was familiar with, with my own music - and I recognized the differences. The Momentum amp's had better bass but were dryer. By this I mean the didn't convey the acoustic performance as naturally. While I'm an engineer by profession - I won't begin to pretend to quantify what was occuring (or wasn't occuring) that made the presentation slightly less real but it was easily noticed.
Thank you once again whitecamaross and all those who contribute. I hope this thread provides each other with shared experiences we all gain from - I know it does for me :-).
Merry Christmas and Happy New Year. It's the best time of the year!
Safe, healthy and Happy Holidays to all :-)
So it is a great thing my last post was removed because i gave Maplegrovemusic a piece of my mind.
I am going to just say that @maplegrovemusic really is beyond ridiculous. I’ve been to WCCs house, met his wife, daughter, and have seen his room. The man is in crazy back pain from all the herniated discs he has from lifting so many power amplifiers off the floor. These are the amplifiers that he shares his views on here for ALL OF US to read.
Meanwhile. you come here to bash or create an entire scenario without ACTUAL FACTS of what you are saying? WCSS probably has THE BEST STUFF i have seen south of West Palm Beach. i was there and saw first hand all the messages, calls, and even DEALERS who call him to ask him what lines they should take on.

As a matter of fact, i was there listening to the boulder 2010 a few weeks ago and the dealer who he bought the Alexia 1s from called him and asked him what his thoughts were on Boulder gear because he is thinking about bringing the line onboard. I know of other dealers who asked him if they should get the focal line, etc, etc. This goes on and on and on! . Why do you think this is? because he KNOWS what he is talking about. He knows with REAL LIFE HANDS ON EXPERIENCE which is something that only a few here can really say they also have. The only experience some people have here is flipping through pages of a magazine and reading and touching the pictures of a component they will never see in real life.
When you bring comments like that just for kicks, it really shows a lack of respect in my opinion. You don’t have to agree with ANYTHING he has to say about components AT ALL. Don’t worry, he does not need your validation or anyone else’s validation. He should be charging for the advice he is giving and i’ve told him to start his own YOUTUBE channel and collect on all the advice he gives. Enough said
Whitecamaross - I wasn't thinking huge amounts of profit . Maybe 5 or 10 % which is a nice little stipend on hifi gear . 
I did just do a google of hifi in florida . Very interesting finding so far . High end Palace has a online website with a used room . So far I Seen the Dynaudio c4 platinum , Martin Logan Neolith , jeff Rowland 925 monoblocks , pass labs xp-30 , Dan dagstino momentum integrated, dcs Vivaldi 1

YOU HAD ALL OF THIS IN YOUR HOUSE RECENTLY !!!!!!!!!!!!!!!!!!!!

Here is the link folks

avrcr79 , Why are you getting all upset for bud ? This in not a accusations of a crime . Its perfectly legal . just not transparent and all of whitecamaross posts are biased and worthless now
