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!

WC, would you not expect two "perfect" digital playback systems to sound exactly the same?  Perfect meaning they are neither adding to or subtracting from (editorializing) the native sound. 
Sorry in advance for this long (for me) post and if it seems I am going off thread it was not my intent.  In fact I am having second thoughts about posting it.  WC, if it should not be here give me the word and I will willingly delete it.

Jafox, your reading much more into what I am saying.  I am anything but an experienced audiophile like all of you.  The best I have is a Musetex-Meitner transport/modded DAC, which still sounds better than my newer player.

Say there is a person in front of you singing.  It is being recorded and faithfully made into a CD.  You play the CD on two different cd players or DAC/transports of vastly different price points.  To me, everything about the sound/special cues, etc., should exactly match the original recording/CD without editorializing.  Regardless of whether the budget or high cost unit playback is closest to the original recording/CD, that is the best sounding unit.  The goal of both units should be to reproduce the original sound exactly.  At what price point will the two units achieve this playback accuracy? I have no idea, but suspect its a lot less than the most expensive units sell for. 

Now of course I agree with you that normally the high cost units will sound truer to the source, if not more analogue, but who has or how can this actually be tested to be true?  Then again, what if the more expensive player makes the music sound better than the original recording but the lesser unit is truer to it?

And last, as you mentioned, it may just end up being that WC has some cable/other that is preventing the Lampi from shining.
Truth is an absolute defense to libel claims, because one of the elements that must be proven in a defamation suit is falsity of the statement. If a statement is true, it cannot be false, and therefore, there is no prima facie case of defamation.
I was wondering if any of you heard any Salk or Daedalus speakers, if they were at the show. I just think the Salks are OMG beautiful and while I have never heard one I have never read one bad word about them.

This is wrong in a way, but I would have pride of ownership at just owning such a beautiful piece of gear, knowing of course that they must sound really good.
klh007, your user name reminded me of the KLH model twenty four combination amp/radio/turntable I had a lifetime ago. Turning that tuning dial was just so silky smooth. Just so enjoyable to own back then, and to guy with my funds was like owning a Cadillac.

Sorry for drifting off topic.
Mr. viber, would you be surprised to learn that you make a post for every 2.5 posts that WC makes?

I am a numbers guy.

I guess you are Ed McMahon to his Johnny Carson.


viber, you are missing the bigger picture.  WC is trying out tons of gear, based on what he wants to try, based on his hunches of what will sound good, forgetting specs, reviews, and each piece of equipment's architecture, not to mention price. It is his desire and ability to jump into the fray and report his experiences which makes this thread unique and really fun.  We are living vicariously through him .

Your the opposite, in every post you grind equipment's specifications into us, you lecture us on what music sounds like, where to sit at a concert. You tell us how big the image is suppose to be, how big the speakers should be, how we should listen to and test our equipment.  Your real message is to follow the viber way or you are lost.  You aren't the least bit concerned that you have crashed someone else's thread. If you didn't make so many posts on someone else's thread it wouldn't seem so out of place.  But as I mentioned above, you make a post for every two and a half WC posts. 

I apologize for bringing this up, but you ignore these anyway.



Note the brand new never out of box but preowned focal Utopia III Stella EM for sale here for less than half price.  Seller appears to be from Holland.
WC, sorry if this is a little off topic.  But RIAA, on a different thread you mentioned your received a XA25 as part of a business transaction (I think) but doubted you would ever use it.  Wondering if you tried it?  If so, your thoughts?
Sorry again WC if off thread, but RIAA, after all the fantastic reviews I can't fathom how you could have resisted hooking up the XA25 and taking her for a spin.
riaa, …."Why on earth would I feel compelled to use it? Im sure its great bang for the buck for people that are financially challenged."....

Not sure and it is not my business what you as a purchaser of the SIT-3 needed to shell out due to the limited production run, but my understanding is that its retail on the SIT-3 is $4K, while the retail on the XA25 is $5K. 

qu'est-ce que c'est?



Respectfully riaa, I have been on A’gon for 18 years, not so sure that I have an excessive amount of posts for that amount of time, but even if I did?

Again, respectfully, one can’t help but notice that 99% of your posts are on WC’s thread, you must really like him a lot? Is he a friend of yours?

I have the means to buy whatever I want but I am actually happy with my simple music system. I am a certified public accountant having just retired from directing a large corporate tax department. 
mrd, I am somewhat taken aback.  Things may be different where you are.  But up here in the green mountains of Vermont a person would not call another person he does not know well a nag without expecting a very serious reaction.

RIAA, I am sorry if I upset you, I did not know about your hearing problem.  The only reason I was asking you is because I have enjoyed reading your posts, had I known I wouldn't have, it was all just meant to be fun.
viber, I was thinking about purchasing the Double Impact, thank you for pointing out that
Perhaps the single array models are brighter than the double array models, which may make certain bright recordings less enjoyable to you than the double array models would.
Now I am not sure which I will purchase.





Well, actually, memorizing the Kama Sutra is a pretty cool trick in itself.
Ha, I wouldn't dream of it either.  Actually you are the most extravagant audiophile I have had the pleasure of reading the adventures of.  I have to say that just the effort of physically lugging equipment around, unplugging/plugging must be a bit of work.  Thanks for taking it on!
Hi WC, not to kick the hornets nest, but having just read a little about your preamp, I was wondering why you chose the 2010 versus the slightly newer 2110?  Not that I know the difference between the two except for the Stereophile review.
Techno, 41 posts, 40 on this thread. Kind of like the tick complaining he doesn’t like the blood of the host he is sucking. Viber, sorry, but you really do know when to say the silliest things at the most inappropriate times.


techno_dude
There are many online 30 day trial dacs , so you won’t lose anything as you can return them easy.
Sure man, do you actually think that a quality individual like WC would stoop to such classless tactics?

Hi techno_dude, I think you should probably face the reality that if WC wants to say what he believes the build quality of a product is or is not we readers following his thread and videos want to hear what he wants to say.
Hi WC, I have been following and enjoying your posts here and the videos now from the beginning.  So take this as just a friendly question, and sorry if you have addressed it earlier and I missed it.  The only thing that throws me off on your videos is that you are not in them, only your voice.
Hi WC, after watching your video of the Florida audio show through my modest system hooked up to my computer I took out my Grados to listen again. At least using this this modest setup the $7k Raven Audio system sounds so good. The more expensive Raven Audio system, again over my desktop system and via Grados, sounded only slightly better, because of the impact on lows of the subwoofer. 
Mrdecibel and jafant, simply and gently put as possible, as a colleague of mine use to say, "your over egging the omelet". 
techno, I am so glad you are so sensitive and at the same time strong and can see through that WC guy and his mini me viper. Guys like us should stick together and we can show them all where it is really at. Keep it up brave warrior.

A lot of us look to you to represent us.

I wrote this back on 9/11, it was suppose to be cynical irony, but now that I reread it it does not come off that way. To be clear, it’s unfortunate that techno believes that he has nothing interesting about himself to share and has settled to be a remora off WC’s thread.

More than anything, what has occurred, and not just on this thread, is that a few posters who would benefit from professional guidance have joined our ranks. The great misfortune is that they will take this as some type of criticism, rather than the opportunity to improve their satisfaction with life that it is. 






@carey1110
It’s the National Enquirer of Audio.
I don’t think you realize it but your post is not so polite to WC. Have you not read and comprehended the detailed descriptions and comparisons of equipment that he has labored to provide for us? There are only a few posters that cause the "friction" to which you refer, and it is certainly your choice if you would rather concentrate on their contributions over the main subject matter of this tread.
carey1110, truth be told, I do understand the comic value of this thread also. Just didn’t want WCs feelings being hurt for all the work he has put in here. But that you know Jay has me wanting to remove my post having taken it all a bit too seriously. Have a great day.
cleeds, after all these years of his great postings, even if WC should make an occasional mistake, we would rather listen to an expert. There are plenty of threads where negative attitudes are welcome.

kren0006,
That is exactly the point. I’m paying attention, but you’re not getting it.
Excuse those of us who may think otherwise, but kren0006 is the one getting it.  







kren0006, I agree with what you have posted. You are not alone in your perceptions.
thezaks, I have already read your post to krenooo6 and I respectfully think its basic premise is incorrect, whereas krenooo6’s opinions on the subject are 100% aligned with my own.

Let’s just agree to disagree and let it go.
viber
Practically speaking, most people who are going DAC direct use their volume controls at middle settings, where there is significant attenuation, chopping off lots of bits.
Not questioning the accuracy of the statement, but just wondering how you happen to know this?





Many people are eagerly awaiting the experiences of people who have compared Be and stock tweeters on Tektons.
I thought so myself, and then realized I was wrong.
@grey9hound
I think that you are more of an equipment junkie and not necessarily a Music fan.
Hi, I have read this entire thread and I can’t recall anyone even once wondering what you or that dudey guy "think". Maybe I missed it, will have to go back and reread it.




+krenooo6

thezaks, I know it may be difficult to believe, but we actually have been getting along on this site for years and years (almost 20 here) without a primer on how to post.
It would be nice if viber accepts WC’s challenge and buys the benchmark. If by chance he is what he portrays himself to be it should not be an economic strain. To put this benchmark issue to rest after what seems like years of reading v's same identical message will be a blessing.
+++ron17, assuming that Jay and viber are good with it that is a brilliant idea.  While we have read hundreds (ok, over a thousand) posts of how good v's system sounds, we can listen for ourselves.

Heck, he can even record himself playing the violin and then play it over his system so we can hear how the "real" unamplified instrument sounds compared to it being played on his system.

@grey9hound  

Are you saying that speakers need to be broken in to sound their best?  Thanks for the heads up.
@ricevs, its pretty simple, start your own thread so you are not intruding on others. Don't think it’s an insult, the chances are once you do you will love it because it’s interesting stuff and I for one am interested in reading about it.
@viber
You will thank me.
I suspect hell will freeze over before that thanks will be forthcoming. I believe you know exactly why, 

@kreen0006
To all who get annoyed with his repetitive shtick, i’d give the same advice others gave me when I used to fly off handle at his wild contentions -- just take it with a major grain of salt, or skip over it if it bothers you.
It’s not happening, my kumbaya days are long since over. And there isn’t a person on the planet who has not or will not lose their father, isn’t relevant.




@viber6
Skepticism is fine initially, but continued bashing and sarcasm over my recommendations is inappropriate. Some people will remain close minded and enjoy bashing rather than opening their minds and listening for themselves.
No, I believe you are the one who doesn’t get it. We started with open minds to your opinions. Now that you have repeated the same two or three simple concepts over pages and pages seemingly a thousand times it is simply boring to tears to read one more time.  As well as implicitly it displays your disrespect of our comprehension skills.

But you will be repeating them again, you just haven’t any fresh ideas to offer.
Right rh67, you have 238 posts and virtually every one of them is hawking the AGD amp.  Hard to take anyone seriously who is one tracked or a manufacturer of class D. 
rh67, that is a great recommendation.  If Underwood HiFi was to send an AGT amp to Jay for testing, and he was to give it the big thumbs up, I would be very tempted to buy one, and I think others also.


viber, I don't get around to viewing this thread every day.  I remember you are going to make a video showing the quality of your system.  Can you spare me a lot of time searching here by telling me the date that you posted it?  I am looking forward to where you finally proved your comments about its qualities that you have often mentioned.
@ricevs
I hope you are not planning to leave this planet soon.....because even this year class D may have equaled the best of class A. We shall see, very soon. Class A......soon to be boat anchors.
In a professional setting, anyone who obsessively repeats the same message to the same audience, failing himself to comprehend their retention levels, would be gently said "Goodbye" to.
