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 think I may have found it. I need to live with it some more. 

The presentation above is still missing a good powercord on the music server, calibration of the transparent cables, more burn in on the master preamp. You are hearing rawness but the immediate potential is quite obvious. Big big things coming. 

Too many variables to say. What i can share is that i had some people come over yesterday to hear these amps and everyone loved the brute power, control and soundstage. I am starting to understand music more and more now because of these amps, but i still need to fully accomodate them in my system (not there yet).

I am also using the VAC preamp which might not necessarily be the very best match for it ( i wont know until i try other preamps). However, even with these challenges, i can feel the untapped potential.

The QKORE was a mind-blowing experience with them too. If i remove it from the system, there is less bass and the intense imaging is lost. I spent nearly 3 hours yesterday trying to figure out why the system was not sounding great when the day prior it was incredible. Long story short, i had the ground cable unplugged from the back of the Master preamp. As soon as i plugged it, it was as if someone turned the lights on within the presentation. 

Mystery amp/preamp are now packed up and ready to ship out next week. I did take enough video footage and pictures of both pieces for when i decide to reveal what it is. I plan to buy another set of both pieces at some point in 2022. I sold them because i needed to make a move when opportunity knocked at my door in order for me to move into these monos that are now in the room. I have zero control on what is available to me and i need to be ready to make moves when things come my way that i am interested in. If someone called me tomorrow offering me a pair of XVX, i would also pack up the XLF and ship them out without notice. If i was offered a pair of relentess or boulder 3050 monos, etc, etc... the same thing would apply. The more i am exposed to, the more i get to understand what each brand does or doesn't. This is extremely value to me and my understanding of the different approaches to sound reproduction from each manufacturer. 

How about...there might be a conflict of interest with dealers that carry the mystery gear and until that gets cleared up I don't want to step on toes. 

I am not, but that doesn’t mean i may not be interested in a specific product that i could potentially import and become a dealer for IF I FEEL IT IS AMAZING on all counts.

If i haven’t mentioned it, it is because i prefer to stay neutral in order to avoid the confusion even though I don’t represent any brands at this time. If i ever decide to do so, i will be front and center and be completely transparent as well.

Having a brand that i might believe in does not mean that the rest of the brands I've owned are no good. I can stay in my lane and continue to give my input on other products in my room. I wouldn't be with a cheerleader outfit cheering for whichever brand i may decide to represent some day. 

A dealer will push what they sell and that's never my approach. 

I can give my opinion on anything I've owned without having to force any brand on anyone. Also, who said that this brand is priced around most people's budgets? It may not be...

 

 

Understood and people can see me as a dealer and I’m ok with it. I can’t let that affect me or I’ll be in the same pond for the rest of my life and these folks aren’t fishing right next to me to comprehend what it feels like. Opinions will be part of life no matter what. You can give away everything you own today and someone will still complain. It's the nature of us human beings. 

Time is of the essence. I gotta push forward and i can’t sit still doing this for the next 8-10 years: still in a small rabbit hole.

Everything needs to move forward. It’s no different than holding a job. Who wants to keep doing the same job with zero aspirations of becoming a manager or director or whatever is considered the next step up ladder from where you are today?

I’ve done 5 years of this folks. I can’t keep throwing the same fish hook in the same pond. It would be nice to eventually go into deeper waters. I’m naturally a person that needs change and never feel comfortable doing the same thing for too long.

A close friend of mine told me something that I’d never forget and which he practices successfully: if you are at a job doing the same thing for 3 years with zero promotion of any kind, you are wasting your time and are falling behind.

Arnold Schwarzenegger claims one of the recipes for his success was to never sleep more than 6 hours or else you are already behind in your day to day.

I started this thread in my 30s and now I’m in my 40s and i don’t and won’t be doing this exact same thing when I’m in my 50s or i failed myself. Bigger things need to happen or I’m not doing something right. This is NOTHING ELSE other than me wanting more FOR ME because I’ve put in 5 years - not 5 months or 5 weeks. I could have finished a few masters degrees during this time. Finding ways to move up are quite limited but i can’t let this take me out. It is all on ME how i can improve content, diversify into other things and find better ways to be productive. 

Amazon started selling books and look at them now? What would have happened if they only stuck to selling books?

Dealers should talk about what they carry because that is why they are in business for. Imagine if you walked into a bmw dealer and asked about audi? What do you think would happen?

It’s the same thing... I don’t think they are wrong for praising what they sell. It is the buyers responsibility to do their homework.

I also feel that they provide the opportunity for you all to hear the system before you buy it. I am the only mad man 😅 who buys blind folded but i think that is also starting to slowly change. 

I think that would be a question for WBF... just make sure you ask an actual user and not a dealer or distributor..I don't think many folks here roll with that caliber of gear although there might be exceptions i am sure.  

The Taiko is awesome indeed, but the break-in is indeed painful. Some days i love what i hear and others not so much. 

 

Do you all remember how a few months ago i had rated the Gryphon Essence as the second best amplifier from the Gryphon lineup? Well... stereophile just rated it as the best amplifier of 2021... My perception of this amp was SPOT ON and theirs seems to also align with me. If they had reviewed the Mephisto then I’m sure it would have won the best amp of 2021.

The level of exposure I’ve been through with regards to amplifiers has allowed me to easily identify when something is special. This is unfortunately something that is only developed with experience. Reading a magazine will never give you the full scoop of what an amplifier is capable of.

It’s important that you all communicate with people who have owned and lived with the component you are considering to buy. Forget reading opinions from those who simply read but don’t buy. I’m not saying that my opinion will be the same as yours but if i tell you something is special, you can bet that you will  probably will be impressed by it 9 times out of 10.

I need to make a video today about what i am hearing with local files. WOW WOW WOW. I can’t believe the difference in sound quality between streaming and playing local files. I don’t even want to stream more music from Tidal or Qobuz.

Greyhound sent me a hard drive over a year ago and i have begun to slowly drop these files into the Taiko server and i just can not believe the sound quality.

More to come!

I had told Emile that there was barely any difference but then i returned 3 hours later and it was quite apparent i was wrong. 

Mike at Suncoast audio also did this exercise and he also said the same thing. The gentleman who sold me the vac monos has Rockport Lyra, full Odin 2 cables, 4 chassis ch precision linestage and he said the difference is drastic. He was the one who told me to try to play local music and find out for myself and yep...he was correct

Impossible... I wish i was wrong... The density of the music and impact is so much better with local files. 

@henry201

Not sure what you mean by "now that i finally have a good front end" as if i haven’t had a good one before 😂

 

It was great. If you don't own a music server and have been using a laptop or something like it, i highly recommend it. There's no doubt that the improvements will be substantial. 

I didn't know there was a timeline for things? 

In my current state, with my equipment and maybe due to the taiko's transparent sound, i am hearing the big difference between both formats. Also, it has been quite a while since i revisited my local music collection. 

It's all a learning process. It doesn't matter how long it took. What matters is the fact that we all learn. 

Yes, if you can upgrade to the n20, it will be a marked improvement. It's almost impossible to go back once you've owned a music server. 

I just don't have the bandwidth to sustain all the work i do here plus doing the tweaking/ fine tuning needed with Vinyl but i might do that some day. I like the convenience of streaming and that is really the main reason why i am still doing it. Imagine doing all the work i already do with my digital front end and then having to buy vinyl and change cartridges, tone arms, etc etc...i would never finish...

I will be releasing the very first interview that Emile - (Taiko Audio's founder) has ever done on Youtube. I am glad to be the first person to interview him and i hope you all enjoy this. 

I plan to release the video around 215pm Easter Time today. We went over a bunch of interesting topics which include his take on power cords, isolation devices, future plans, and if there will be a new more affordable music server in the future!

 

 

Heads up:

If you own a magico S series and have been thinking about selling it, now is the time to do so. The new S series is releasing next year.  

 

Here are the Shunyata omega PCs for the first time in the system. These have no miles on them.

Are we getting ripped off with the ultra high end? Are we overpaying? What is our responsibility as buyers? 

On my next video i plan to talk about certain areas that are often not talked about. Don't miss it 

we are about to find out my thoughts on this 2 part video series. 

video will drop in 30 minutes. Do not miss it!

I still feel that monoblocks costing 200k should NOT be scared to drive any load. I have owned several sets of monos that wouldn’t melt trying to run the Alexx. Mephisto and Boulder laughed at my Alexx speakers. It was no problem for them to drive that speaker. You could have a point in terms of the difficult load the Alexx V presents but that should be a concern ONLY if you plan to use amps that are incapable.

A 200k amp should never run and hide. To me, this is a straight up rip off. Oh and guess what? These 200k monos were replaced by the Mephisto monoblocks! Isn't that interesting?

 

Wait until you all watch part 2 of this video.

I feel that no amp costing 200k should run and hide from any speaker. Mephisto mauls speakers for a living. 

 

@david_ten 

No I wouldn't say the more power the better the amp. For instance, the Gryphon Essence has less power than the Luxman 900u and in my opinion it beats the Luxman all day long. 

@pokey77

You nailed this with your comment above.

The XLF is easy to drive and make it LOUD but this doesnt mean it will be displaying its full capabilities. That is far from the truth.

Making a speaker play loud IS NOT the entire picture. I’ve heard my Xlf play loud and sound directional like a panel speaker but then you add a serious amp and wings come out the back of the speakers and now the speaker isn’t in the room anymore.

I have a video coming soon in which i will be talking about THE IMPORTANCE of selecting the component you want to build your system around. This holds THE KEY that many often times fail to see.

Yes I agree. However, it's hard to even assume that magazine reviews aren't doing the same we did of swapping stuff in and out. 

We plan to give our impressions of the playback design 22k DAC versus my MSB Reference soon.
