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, amp stands and many other tweaks have profound effects on the sound, but they are unlikely to change the basic character of amps. Your preference for one amp over another is unlikely to change. As WC just implied, the thin power cord on the Pass didn't take away from its muscle character, the way he described in the video. |
WC, I agree that this was an absolutely terrific review, and I appreciated your honesty and the journey you took us on. I think adding music would actually take away from this raw discussion on the two amps, so I like it as is. As you mentioned, you could always do a separate video with music. Plus, if you had music on this review, you might have a few pages of folks complaining or praising your music choices, it's too loud or too soft, etc, etc. Much appreciated and thanks for the privilege, Dave |
Actually, WC, equipment stands and racks, do have an enormous effect on the sq of gear, and I can pretty much guarantee, anyone owning the level of amps you own, and are reviewing, will not have them on the floor. I also want to interject, that throughout the video ( well done, btw ), I heard some descriptive words of yours that were contradictory between both amplifiers. The bottom line, however, was, that you preferred the Pass. And, the most famous statement of yours, which you have said 100s of times......" I can easily live with this, and just allow the music to flow, and be happy ". Well, this has not been true, yet, nor will it ever be. It is part of the sickness you have ( lol ), and the fact, it is still not about the music, but the equipment, and the entertaining journey, you and your followers, are on. I also feel, music playing, will not matter, so, leave it as it is. Continue to enjoy, your journey. Always, MrD. |
Well I think you hit the exact sweetspot with the Pass/Dag video in terms of content and detail. Best way I can describe is it seemed like a compilation of your posts on this thread - raw as you say - which will be what garners support. My opinion but playing music is not needed. It’ll never sound decent and then people will just quibble about it. Plus it’d be boring. People either will decide whether they trust your opinion or not. Most reading here already do. If they don’t trust what you’re saying, they won’t take your advice, and that’s fine. But playing music that won’t come through quality wise isn’t going to change their minds. They’ll just find a new thing to bitch about. You hit it right here with this video. Giving your honest opinion on two pieces. It won’t match everyone’s, but that’s okay. Just like the 180 pages of this thread. Bubbly personality not needed - just the emotion that came through in 4th video of you doing what you love - comparing high level equipment- that's all you need |
Thank you guys for all the feedback. I will say that yes i don’t have the "bubbly" personality that some youtubers have, but maybe it is because i am a former military man? kinda hard to go from being structured and all business to an all picturesque personality (at least for me). i tried to be as raw as possible which i know it is not necessarily a good thing for some of you, but some do like it. That said, i do understand that there are things that i could have added such as: -Fuses -more stands -stillpoints, -metal blocks on top of the amps (or whatever they are called) -10 different sets of power cords ( in order for me to drive myself crazy and never really end a review because i will be trying powercords 24/7) - different outlets - different fuses on the circuit breaker -etc -etc -etc -etc However, please know that i simply CAN’T also go through that because that also becomes a trial by itself. That becomes an entire new journey which i haven’t really done. If i were to now use this stand, that stand, the other fuse, this powercord, the other powercord, then when does it end? i can’t sustain that "tweaking " aspect. Do i think that putting the pass labs xs300s on the floor just like the momentums would have had a different outcome on my findings? probably not. I want to pull a product out of the box, give it ample warm-up time and then put it through its paces. Maybe it is my fault for not being clearer, but i won’t be embarking on tweaking other than maybe a power cord change (Nordost Odin 1) or XLR and that is about it. I am essentially taking the car the way it comes from the factory and taking it to the track. I won’t be putting on slicks, suspension, exhaust, supercharger, etc in order to see how fast it can go. That is for the person that has the time and money to do so. I will continue to give you the raw results and it is for you all to decide if YOU want to embark on the expensive tweaking journey if you decide to buy any of these components in the future. I am simply reporting on the "raw" potential of a component. Let’s face it, how many times have you all read a review and did not even know if the amplifier reviewed was also sitting on the floor? did they always mention they did a fuse swap? no right? a different outlet? so for all we know they are doing the same thing i am doing here and we don’t even know, but i am just being open about it which is something that can’t be said about many magazine reviews. A lot of these tweaks are left unknown. So going forward, remember, i am reporting on RAW potential. At the end of the day, at turd is a turd even if you polish it right? I have not seen an amplifier that went from being garbage to being an world class amp just by doing a fuse change and a power cord swap. You should be able to quickly detect if something is indeed special and this feeling is exactly what will make you feel the need to go the extra mile by refining it using tweaks. |
Wow, that is a damn fine video. It was exactly like how your posts have been on this site which is why the thread was so popular. Honest, straightforward, assessment of strengths and weaknesses and direct head-to-head comparison. Very well done. Keep it up. What I liked about the presentation was the emotion and energy. To be honest many of first three videos sounded like you recorded them after being awake for 18 hours straight - you sounded kinda tired on first three vids. But with this fourth one you were not doing background crap or a history lesson -- you were getting into what you do - review and compare amps!! That came thru big time and was so much better. Thanks! |
Interesting personal account. As far as upgrading your recording equipment, you don't need fancy editing, etc. Just plan ahead and rehearse A/B matching of sound levels to allow for different gain of different amps. Don't go by specs because different tonal balances will affect subjective SPL. Do it by ear. Choose a brief 1 minute excerpt that illustrates your points. But the best external mics with placement in the sweet spot as you would listen is the most critical factor. Some people have good computer audio and would appreciate hearing for themselves the subtle differences you find. The sound still wouldn't be as good as sitting with you live in your room, but the opportunity to replay the A/B tests as often as you want would be invaluable. Even with friends doing live listening, there is a limit on how much patience friends have with each other, bending over to change connections repeatedly, etc. That's the value of high quality recordings. |
And the winner between pass xs300 and momentum is ?????? Click below to find out:) https://youtu.be/eLNZ-fmUUis |
WC,I apologize if you've spelled this out already and I missed it, but I was wondering how the info will come out on your equipment going forward. Will you comment here first and the video comes out later? Or will the video come out first and then discussion to take place here after that? Thanks,Dave |
My small amps don't get very hot, so once they are broken in I listen as soon as they are turned on. There are no signficant changes after they are on for a few hours. I think few people keep power guzzlers on all the time, so for practical reasons they want the amp to sound good nearly right away. Let's hear how the Dag and Pass compare soon after turn on, and what sonic characteristics change when on several hours later. |
Heat issues aside, the only negative I believe I've heard from WC on the Xs amps is that they really hit their stride after 5-6 hours of use. That means shorter listening sessions might not have the utmost sound quality (unless the system is left running prior to the listening session). I suspect then that if the m400's hit their stride quicker and have nearly as good sonics, then they have a good chance of displacing the Xs amps from their throne. Of course, if they are better than the Xs amps, then it's a no brainer. Dave |
@chazzzy007 Thanks for the follow up post. Did you own both the SA-103 and the SB-301? I was looking at trying one or both of these out curiosity. I had the Plinius SA-250 Mk lV in my system before and really loved it overall as it did almost everything I need and never mind especially for the amazing value to ear proposition, "WC hit it on the head". I owned a SA-250 MK lV and it also ran hot in both class A and A/B but not scorching as I gave it plenty of breathing room. Not totally sure but I am guessing that the SA-103 will be more like the SA-250 with less power so I'm thinking of trying the SB-300 1st. and give it a run as a consideration for an in between/2nd. system as I 2 fall in and out of love with my toys and move on to the next greatest adventure. |
Sure, So I’ve always said that I believe plinius is one of the best bangs for the buck considering what they sell for on the used market. I believe they have the highest price/performance ratio. They are well built, they have excellent high frequencies with great musicality. I don’t really dislike anything about plinius other than the fact that they run extremely hot. If you want bottom end control then grab a plinius sb301 mk2 , but If you value highs over lows then grab the sa103. Those models have been discontinued so they should show up on the used market at very good prices. Also, those amps benefit tremendously from good powercords so don’t be cheap. Buy a great powercord for it. There’s also a modification you can do to the outlet that will enhance its performance ( I don’t know the details on this ). I’d take a plinius over parasound, bryston , nad, theta digital, new krell amps, McIntosh 601, 611, 1.2kw, mc452. Don’t disregard the plinius line of amplifiers. |
@whitecamaross Our friend BluMartini had a question earlier in the thread about Plinius. (Due to the pre-occupation with tdud he had to open up a still unanswered thread) I am looking giving the above Plinius models a shot mating one of the above amps with PS Audio PerfectWave Dac, BHK Preamp and a pair of Focal Sopra lll's. |
You have the right to not agree with my critical side of this thread. May I remind you that I ´ve also written positively numerous times. A forum thread is for exchanging opinions, may they be positive or negative or just neutral. Maybe a blog where have complete control would better suit you ( ego). Let’s get back to topic, for once. |
I’ll return when I’m ready. You’ve been warned that your negative criticism, constant opinion of gear you haven’t heard and lately just simply an effort to attack high end gear for your own satisfaction isn’t really cool anymore. When you throw punches as what you’ve done in the last few weeks, you have to expect that it’s a matter of time before they come back you as you have experienced today. I hope today has given you a good idea of how pissed off some people are at everything you’ve been doing since you returned. I don’t know why you have something against those who have the opportunity to own some of the best stuff out there. No clue why that affects you which is now clear to everyone by your latest comments. You don't want to be known as the guy who hates on others who have more. I said it above, concentrate on you and don't worry about criticizing those that don't affect your life. |
@riaa_award_collectors_on_facebook Poor techno_dude, he should have never brought a water pistol to a gun fight! :(...... |

kren0006251 posts 01-16-2020 3:49amIt’s odd that you’ve had the magico m3s for 10 days now and not a word about them. Are they that bad in comparison to Wilson?WCSS said he will be traveling for work this week... |
You must listen to Pipe and Slippers music cause that's all the AHB2 is good for. Its HORRIFIC on poorly recorded classic rock...like looking at a woman without their warpaint on in the morning...A frightening experience . Im not a Fanboy of any brand and I probably have more Amps here than you will ever have in your life....and only 2 ARC amps. Mcintosh=Harley Davidson. You pay for the brand name but you certainly don't get the quality. Yep...resale value is good. Same goes for Vintage Pioneer, Marantz etc....Prices keep going up. Yet performance wise they lag WAAAAY behind other brands like Sansui, Sanyo and higher end Kenwoods. C47 is crapola. I had the C52 and that was mediocrity at its finest. I also noticed in prior posts made by you that you say you have BOTH of them. We all know that isn't true. |
If McIntosh was not keeping up with the big boys, it would have died years ago and resale value would not be among the very best if not the best. I never rule out a product, based on snobinism. I keep an open mind, because I know they are products out there that compete with much pricier ones. Best example is the Benchmark AHB2 amplifier. It mesures like crazy low thd unseen before... better than most of your ARC fanboy overpriced gear. |
