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!

No worries.   Anyone want to guess "when" WC will reveal this component?

Dave

@deludedaudiophile 

I have found many things in audio that seem unbelievable, until I actually hear it.   That only comes when one can jump from common sense/theory/speculation, etc and enter the world of true experience.  Unfortunately, I can't help there - that decision is up to you.

Dave

WC,

As requested by some folks here, they want to hear comparisons with the same songs, so you end up hearing those same songs over and over.  It becomes an analytical experience, which at times can be exciting for the improvements/differences, but in the end can produce the burn out. 

The direction you are taking - Magico over the Focal as just one example - is to have a system that is able to expose the flaws in the music that is played, as opposed to having most everything sound decent.  However, this might steer you away from anything but high quality music; hence, the same songs over and over.

 

WC,

Nice video - enjoy watching you and Oz discuss things.  

So, you are probably going to compare your new analog setup with the MSB digital setup - both setups have some cost to them.  What I'm wondering is - what does it take for an analog setup to sound better than your MSB digital setup.  For example, can a $5K turntable sound better than the MSB digital setup.  I know there's a lot more variables and viber6 mentioned the cartridge having a big impact on the sound.  Anyway, not sure if you are going to venture into anything like that, but it would be interesting.  I know you mentioned that you might downsize the digital side, etc.   I'm sure the first step though is to see what you think of an analog setup in your system and how it impacts you.  Fun stuff!

Dave

WC,

I remember when the entrance of the Gryphon Mephisto was a huge deal for you, so based upon your comments, the 3000 series must be truly impressive. 

"My gut tells me there is nothing above these two."

Well, there are the 3050 monos  :-)

Dave

@viber6 

I think WC already mentioned in a video that there is not any DAC that has better sound quality than the 3010.   Not sure though if clarity and transparency is the highest goal for WC - he would need to comment on that.  From what I gather, WC likes a combination of attributes and the 3000 series satisfies all of them in spades. 

Dave

WC,

The YT comments are interesting on the comparison videos you put out.   Some folks are having trouble deciding which one they like better.   One person says Presentation 1 sounds sweeter and the next person says Presentation 2 sounds sweeter.  Anyway, looking forward to the reveal.

Dave

@clearthink

A nice thought about high resolution audio files on Drop Box, etc.  However, I think the idea is to get folks to watch the videos on YT and to continue building the subscribers.   If WC provided these high resolution audio files, then some/many folks might skip YT altogether and only use the high resolution files.  This would somewhat defeat the purpose for the YT channel.

The only alternative I can think of is something where WC can charge monthly for the high resolution files. 

Dave

@rpeluso

Not sure I understand the response.   I do understand however that a person who puts in hours and hours week after week of putting together equipment/presentations, recordings, working out sales/purchases, consulting with folks, etc, in addition to day job, family and personal life - that person deserves the chance to make a buck for their efforts.

Dave

@carey1110 

I think in WC's video, he mentions that those watching the videos seemed to favor the presentation with the stock power cord.  I know it's a YT video, but WC confirms by mentioning that a high end PC is not necessary. 

Having said that, this seems to be an exception (the 3010).   I am guessing that just about any other pre-amp that WC has tried will benefit from an upgraded PC.

Agreed though that everyone has different tastes and listening preferences, so you will always have folks that sit on either side of this.

Dave

@maxima95 

I don't think he's trying to hock his wares in this case - just providing info for folks if they want to try a lower cost alternative to the Stromtank.  Like he mentioned, he's not making any money on it.

Dave

We know two things for sure :

1) WC has not tried/heard ricevs suggestion with inverters, so he cannot absolutely say that one is better than the other.  He can speculate.

2) ricevs has not tried/heard a stromtank, so he cannot absolutely say that one is better than the other. He can speculate, but he's indicating that he is interpolating - based upon a reviewer's comparison of a Stromtank vs. an inverter, then comparing other products to what the reviewer used that are supposed to be better products. 

The way I look at it, anything is possible, but when putting pieces together as ricevs is suggesting, synergy will come into play, and the end product might or might not be as good as he suspects. 

With that in mind - I see that ricevs mentions that he does not mind begin wrong about his speculation that this DIY setup would be better than a Stromtank.   That indicates to me that he is open minded about the comparison.   To me, this is respectful and an interesting option - it would be fun for someone to try it out.  Even better for all of us if WC tried it. 

All of this is regarding the performance side of it.  Regarding the appearance side of it, the form factor of the Stromtank wins in my book and most likely with my wife  :-)

Dave

 

Don't blame you WC.   I mentioned it would be fun/better if you tried it, but selfishly, only so that we can hear the comparison.   Your money spending is your decision - I definitely don't want to be guilty of telling you how to spend your money, and I'm not trying to do that.     Plus, the stromtank is a nice form factor comparatively.   Not sure how you would fit the setup that ricevs is suggesting  :-)

Dave

So WC, do you prefer Tidal or Qobuz?  Or, will that be a future video :-)

Dave

WC,

You mention that the You're getting hustled video would typically have been for members-only content, but you put it on YT to show us what you can get as a member.  My only comment is that, for this particular video, why would you want this to be for members only?   This is basically a sales presentation for the Stromtank, and I would think you would want as many folks as possible to watch it - not just members?   Maybe that's why you made the exception to put it on the public YT?

By the way, it's a good sales presentation, so don't get me wrong.  If I was buying $5K or more power cords, plus a conditioner, plus a power cord for the conditioner, then I would definitely want to consider one of these.  Well done, and it makes complete sense.

Dave

WC,

You've been through a lot of power conditioners.  If someone's system is a lower priced system and/or their cabling is not high end (high priced) cabling, then a $15K-$20K stromtank might be desirable, but not in the budget.   For those folks do you have a recommendation?  I had thought you mentioned at one point that it might be best just to do without a power conditioner, since it adds a flavor.  Or, perhaps, you have some recommendations?  

Dave

Great points you made WC!   I cling more to the subjective, when it comes to audio.   If it sounds good/better to me, then that's my preference - it's all based upon what "I" prefer.   And I can define the differences in what I hear between different products - based upon my subjective listening.  I am not as worried as to "why" it sounds better.

This is a big issue typically for the measurement and/or scientific and/or intellectual folks.  They'll tell me that there's no way it can be better, based upon measurements/science/logic, etc without even hearing it for themselves.   So, they always disagree with me.  And I disagree with them, because I'm basing it on what I hear.

There will always be that divide.  I don't mind if someone wants to base their audio adventures on measurements/science/intellect/speculation, etc - more power to them.  I don't even mind if they share their opinion.  I just think it's gone too far when they tell me I'm wrong and I have to align with their approach.

I've seen that you experience the same here - folks who tell you your wrong and you have to do it this way or that.  This is about your adventure, and you should do it your way.  I 100% respect that.

Dave

I agree with viber6 that it would have been nice to have the same music on the last two videos.  Still,  I prefer the sound on this last video over the video before it.  Can possibly make a good case for the Stromtank with factory power cords :-)

Dave

I agree that it's difficult to compare, when the songs are different on each video.  Still, I do like the sound on this video.

Dave

I suspect WC likes to listen to different music and not the same old stuff over and over again - might be a reason for different music on the videos.  Not sure what WC's expectation is though for his YT and A'gon audience for these videos with different songs??    I just take it as fun and listen to the videos, but I definitely won't be coming to any conclusions with different music on the videos.

Dave

Hey WC,

When you visit Magico and Alon, are you going to ask about one of the negatives of a Magico speaker - the expense of replacing a driver?  Or, is this just a given and the Owner needs to account for that?

Thanks,

Dave

@clearthink

I walked into the basketball gym and two guys were playing 1:1. Both are great players and many of us wondered who would win. Lots of us saw different things they were doing and it was fun to talk about it. At the end, everyone had a fun time with it.

One guy though (let’s name him Dude) pointed out that the rim might be slightly bent downward, the floor wasn’t perfectly clean, the humidity level was higher which caused the players to sweat more, and he pointed out some other problems with the 1:1 game.

Everyone then realized it was stupid of them to believe that this was all for fun, and Dude felt good that everyone went home disappointed.

:-)

Oh, sorry, actually, what happened was that everyone had a great time and didn’t really care what Dude said.

Thanks for the fun WC!

Dave

@clearthink

Nothing is ever going to be perfect or even approach perfect when doing YT comparisons of products - there are so many variables . Even hearing the same system in person in a store vs. your own home will most likely be different. Yes, WC is sharing his system as he always has, and yes, he now has some products he is a dealer for. If folks want to purchase his products based upon YT videos, well, that’s their prerogative. I’m guessing though that they will get WC’s take on the equipment comparisons - how he hears it in his room - and then go from there. If I can’t hear the equipment in my room before I purchase, then I will typically look at user reviews, as well as have a conversation with the Dealer.

I just don’t see a reason to pick on the YT videos, knowing already that they will never be perfect and never fully represent what’s actually being heard in the room. I liked viber6’s comment about the consistency of the flaws and still being able to compare YT videos. I also like Jay’s videos that typically follow - the ones that describe what he heard in the room, what he preferred, and why.

Dave

@clearthink 

You mentioned that many folks have heard distortion and reasoned that it comes from the AC power foundation.  Who, besides you, have posted about that?   Maybe one other person?

Dave

I don't believe WC mentioned anything about an arc welder.  Sounds like something someone has fabricated.  In fact, this whole A/C thing seems fabricated.  

Sorry, I'm not buying it.

Dave

@clearthink

You might have crossed out the word commercial, but your implications still remain regarding profits from these videos, as well as the implication regarding power problems.

You continue to fabricate things. Let me try one....

You (clearthink) should be proud of the money you make from other manufacturers, with each post and implication you put on this thread. What will you do with your funds?

Dave

This discussion between keithr and rbach is interesting....

 I have to agree with rbach and henry201 (and WC too, based on his comment) that keithr made it sound like Alon does not do any of the design.   I honestly don't think these folks are attacking - just questioning the statement you made.   I think keithr has now clarified it, so  that's good.

And, is it true that keithr has posts on other forums, indicating a dislike for Magico?   If true, then keithr should just own his opinion and not claim that folks are attacking.  If it's not true, then I understand the attacking comment, and I would question rbach's motives.

Dave

@carey1110 

I think you missed rbach's mention that keithr has posts on other forums, indicating a dislike for Magico - that is what led him to think that.

Dave

Agreed on the video production WC - great job!   You make it fun, because you are like a kid in a candy store, and on display is your passion and your humility - just being a real person and treating the whole thing like a privilege. 

Dave

@viber6

Not sure I understand the math that made 3 10’s equivalent to one 14.4"? I typically talk "cone area", but you mentioned air moving capacity - maybe that’s different than just cone area.

Anyway, with regards to cone area, the three 10’s have a bit more cone area than two 12’s. And, there are two speakers, so we have a total of 6 10’s - the equivalent of more than four 12’s. That total cone area will move a lot of air and give a good thump.

I agree though with what you said about the accurate midrange and HF drivers, as well as the cabinet design, as contributing factors to the excellent bass.

Dave

Agreed - stay safe WC!   One of my employees is in Palm Bay, and it's supposed to hit them at 8am EST tomorrow.

Dave

I still refer to him as WC too.   If he lets us know a preference, I will use that going forward.   If he doesn't care, then it doesn't matter.

Dave

WC,

On the website, under My Journey, I see Brands I Represent at the bottom of the page.  I was curious, so I clicked on those links to look at the manufacturer's site.  However, the IsoAcoustics link is going to the wrong place.  Just thought I would let you know.

Dave

WC,

Seems like Luxman really upped their game with this new amp.   I think this goes back to one of the negatives you had about the Pass Labs amps - that they haven't really done substantial upgrades.   I think the .8 series came out 8 years ago. 

Dave

WC,

You mentioned that the 3050's are the best amps in the U.S.  I know you have tried some D'Agostino amps - have you tried the Relentless Epic 1600 mono amps?

Dave
