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!


128x128jays_audio_lab
So my first comment is the Ref6SE from the previous video sounds much better than the Dagostino preamp in this video. That’s observation one.

Observation two was I thought the Maggies not really up to the challenge, especially the first track with either presentation. Not impressive sound overall, imo.

As to Number 1 vs. Number 2, I thought Number 2 was better.
Good feedback. Let’s wait for the rest to chime in. Again, the differences between this video and the previous were:
-Preamp  (Dag on this one )
-I recorded at 78db on this one instead of 83db which is what I did on the last video.
-I also added a different song on this video in the beginning of each presentation
@viber6 I like resolution, speed and as much engagement as possible.The Mephisto is the perfect balance in this regard and the bass control like Jay said above is second to none.The CH M1.1 lacks the engagement not matter what setting you put in, but it is still a killer amp.As of today i have not yet heard a better SS amp than the Mephisto stereo at least for my taste.I'm a big fan of Aries Cerat monoblocks but don't want to cope with tubes and i also like CH M1.1Mephisto is a good balance between Aries Cerat sound and CH sound.One thing to point out is the Mephisto is not dark as opposed to the lower models.All of my auditions were done at dearlers, the only combo i home auditioned was the Ypsilon pre-power combo.
Hope that helps.
WC i also wish you would go and get the Mephisto's.  Surely a shoot out between Essence and Mephisto is too much to ask for but also the Internet's greatest wish.  Hard to imagine how the Essence could fail to impress and then harder to imagine what the Mephisto does better?
BTW, from what I read from the Gryphon site......the Mephisto stereo amp has 500,000 uf of capacitance.....250K per channel. The mono block version uses all the caps for one channel...500K per channel......so, there is one million uf...in a pair of the MONO block Mephisto Solo amps.

The Antileon actually has more capacitance than the Mephisto.....335K per channel. So, a pair of Antileon monos have 1.34 million uf (total of both mono channels)......again more than Mephisto monos.

The Essence stereo amp has almost as much as the Mephisto....220K. per channel.

Read here:

https://gryphon-audio.dk/wp-content/uploads/2020/05/Tech.-Spec.-ALL-Products-05032020.pdf

The Parasound JC1+ has 198K per channel......only slightly less than the stereo Mephisto’s 250K.

https://parasound.com/jc1+.php

Jay, please research your stuff before posting......The stereo Gryphon Mephisto (per channel) amp has 1.26 times the capacitance of the Parasound (per channel).....very little difference.

The Relentless amps have 600K per amp.....or 1.2 million uf per pair of mono blocks.

What this all this means is practically nothing......because, lots of things make for the final sound. You could have 2 million uf per channel and the amp could sound bad. Just letting you know what the actual figures are..
Well we still have to wait and see what Jay's ultimate amp deal is.I wouldn't be surprised if he was able to get a good deal on Mephisto Solos, on the other hand Relentless monos would be a huge surprise IMO.Wait and see.

alright Ricevs:
i think it is time to school you a little. Please grab your paper and pen and take notes: (i will do this one time only and no more will be heard about this from me)
here is ONE of the specs of the mephisto:

-Eight 56,000 microFarad capacitors with low ESR (Equivalent Series Resistance) for a total capacity of 448,000 microFarad/100V smoothes the voltage to the output supply. -

Next
Go to this image:
http://www.theaudiobeat.com/news/pics/gryphon_mephisto_inside_large.jpg

Next:
Count the brown capacitors that are mentioned above. Do you see EIGHT PER SIDE? that means 8 per channel. So how much is that total? Close to a million microfarads rights?

Are you taking notes?

Ok then let me continue. In case you HAVE NEVER NOTICED, any time you have ANY STEREO AMP say for instance that it has 100,000 microfarads per channel, this means that the mono version will have TWICE the capacitance because it is using both channels. You can easily see this if you look closely at the specs of the essence amplifier and compare the mono version vs the stereo version.
Unfortunately, that is a typo on Gryphon's part and on the distributors part. They failed to mention that the specs on the mephisto stereo when it comes to capacitance  are about PER CHANNEL. 

Now, you can go on and take a seat again and let the show continue.
thanks




Maybe I am confused about what jays post about all the amps meant and why people are posting about the amps he might be brining in. A few days ago he posted several different brands and a huge deal, I had the impression all those would be in house with this deal, to compare at the same time. If so not sure why others keep posting about his next move with amps, as the mephisto was one of them. Or could be I just misunderstood that post and doing some wishful thinking, lol.
# 2 for me.
listened once and picked #2, no contest, then scrolled down and saw everybody else did the same. I suspect 2 is the Merill...

Jay,
Mike at Sun coast uploaded a few videos with Fyne speakers, you may wanna listen to them if you haven't already. Not crazy about the looks but the sound, my oh my...
 
Thanks for the Vid....#2 better in every way.  I also think the Ref 6 would have added to the overall sound.
i had the pleasure to hear the Fyne Audio F1-12 and to be honest with you, i was blown the hell away by them. They sound so CLEAR, BIG, WIDE, and have some of the best " you are there" presentation i have heard before.
I won’t say much other than they killed the $60k speaker i heard right after. I had SERIOUSLY considered buying the Fyne Audio F1-12 speaker as a replacement speaker because i couldn’t believe how amazing it sounded. I actually told Mike to do the Essence Gryphon (before he even had it) with the Fyne Audios and he was blown away once he heard this recommendation in his store. I knew that combo would work fantastic for him and i am glad he listened :)

If you were to ask me, this system would work AMAZING:

ARC REF6SE
FYNE AUDIO F1’12 (or the model just below it)
Gryphon Essence stereo amp
Chord Dave/ DCS Bartok
Wireworld Platinum speaker cables

That system above, WITHOUT EVEN HEARING IT EXACTLY AS I OUTLINED IT would put a ton of systems to shame. If you are thinking of putting a system together that WORKS and that will give you tremendous clarity, musicality, detail, liveliness then do the above and i promise you that you won’t look back.
My hard head just likes to make things complicated, but if i had to build a system with my eyes closed without spending as much money as i have, that is what i would do WITHOUT A QUESTION.
HELL...maybe that is the speaker i have coming :) 
You’re doing systems for us to hear, not a forever system, lol. So different goals. The videos I had seen previously of the fynes did sound good
some people are looking for a system they can enjoy and what i outlined above would probably be something that most people would love. I detest speakers that are warm, dull, boring, slow, lethargic. There are many brands that sound like that to me such as Sonus Faber Amati Futura for instance.... Of course there is another speaker brand that comes to mind that i still wonder why people find it nice sounding when not only does it look aesthetically ugly, but it just does not really make me jump out of my seat? yes i have heard it before too... however, to each their own and i gotta respect people’s choices.

The only reason why Fyne audio has not taken off is because it is relatively a new company, but even as new as it is, it is already stumping on some brands that have been doing this for a long time.

Behind Fyne I heard are some ex Tannoy guys. Can see resemblance there, look like modernized Tannoy line to me.


None at this time... I might bring home some McIntosh 901 monos at some point though... 
I like the coaxial design of the Fyne Audio speakers.  The titanium tweeter promises to be outstanding, used down to 750 Hz in the F1-12 and F1-10 models.  Titanium is rigid with low mass, a great combination for a driver.  The F1-10 might have greater clarity than the F1-12 below 750 Hz, due to its smaller 10" driver vs the 12" driver in the F1-12.  What are the MSRP's of each?

Don't ignore the Tekton MOAB for $4500, which uses the low mass tweeter array down to 300 Hz.  The materials might not be of the quality of the Fyne, but using low mass drivers down to as low freq as possible is desirable for clarity.  Ricevs raves about MOAB.
Sounds like Jay is talking about Tekton’s? I have have the Ulfers for my mains in my home theater and have a set of moabs ordered for the rears. 
New video has been uploaded. Back to the ref6se and 2 amps. Let me know your thoughts
Well yesterday I liked #2 amp better but today I preferred #1.....don't know if it was the addition of the Ref6 or what.  Thx for the video.
With regard to the Fyne speakers why the hell would the 10 inch be preferable to the 12 inch model.  The crossover point is the same with greater surface area the excursion will be smaller at any given volume  which equals less distortion,  The sensitivity of the larger woofer will also equal less distortion due to a lesser load on the amplifier and less series resistance on the tweeter.   By this same logic should you choose a Wilson Tune Tot over a Chronosonic?  Viber why do have this thing against bass?  All music is not chamber music, in a large symphonic piece there are tympani's, bass trombones,double bass, bass drums, and pipe organs alll of which are minimized on smaller woofers, this is not clarity, this is removing part of the spectrum so the remaining part becomes more apparent.  Not to even mention pop or rock music where often the bass line is the emotional factor which causes to tap your foot  and sway to the music.  I guess you have never been to a club or dance bar where the music is all encompassing and penetrates your soul perpetrated by the bass rhythm, then again probably not, you would rather Tiptoe Thru The Tulips.  WC I have followed your thread from day one and appreciate your efforts and am sorry to interject here, It's just I and many others here are tired of V's continual spouting off the same old message.  Awaiting your next  surprise!!
shannere,
Much of what you say is true.  For power at higher volumes, the larger woofer is better.  But the larger woofer has more mass, so the smaller one is more nimble and probably has more clarity at low/moderate volume.  This principle of how smaller drivers are more nimble with greater clarity than larger drivers is utilized by Eric Alexander, the designer of the Tekton Design speakers.  The 14 tweeters have the equivalent drive power as a single 9" midrange.  Everyone who owns the various Tekton models, including grey9hound here, has commented on their extraordinary clarity.  I mentioned the Tekton here because of its use of small drivers down to 300 Hz, similar to the use of the tweeter of the Fyne Audio top models down to 750 Hz.  I believe that is a main factor in the clarity of both companies' speakers.  The cheaper Fyne speakers use a different tweeter down to only 1800 or 1900 Hz, and the larger driver below that, so the crucial midrange from 750-1800 Hz would have better clarity from the smaller driver in the top models.

You preferentially value bass in music, which is fine for the rock/pop that you mostly listen to, but most melodic content of all music is in the midrange, with HF providing the needed harmonics of that.  Since bass instruments have lots of midrange and HF harmonics, in order to accurately reveal the total sound of these instruments, accuracy in mids and HF is essential.  Otherwise, the bass sounds boomy and is at best powerful, but without its true articulation.

How much do you know about symphonic music?  With the exception of organ music, there is no deep bass in most pieces from the years 1500 to 1800.  Even after 1800, there is a sprinkling of deep bass here and there, but the main musical content is well above 50 Hz.  There is a popular piece often used in demos, Saint Saens Organ Symphony, which does have organ notes but no lower than 32 Hz.  I admit that the sections of deep organ notes are missing on my system, but I am not willing to sacrifice midrange/HF clarity for most music so I can play this piece and a few others.

Everyone must make choices with compromises.  No system does everything superlatively well.  Go to a live, unamplified concert and sit close to get everything.
My speakers-Infinity Kappa 9's , forced me to have sufficiently high current amplification to drive them .
Notoriously difficult to drive with 2 ohm impedance 
I finally settled on a pair of Metaxas Solitaires and they really make the kappa's sing.
Metaxas is an Aussie designed and built power amplifier and for the price will give the wonderful American amps a run for their money. 
On the second video I'm going with # 2.
Now I'll go watch the last video with your take on them. :)

Interesting about the second blind shootout.
The videos have been coming so quickly that I didn’t get enough time to give a super critical listen to that second one. But I will say that on the first listen I wasn’t able to pick a clear winner.

That surprised me at the time but now it makes sense. With the Merrill out of the mix and the Dag in against the Parasound, that closed up the gap (ie, removed the superior amp and put one in more in line with the Parasound). 

Unfortunately for Dag, yet another indictment of it, as again it struggled to even beat Parasound. I do think I had it maybe slightly ahead if I recall.

Nice choice on speakers. They’ll be a bit of an upgrade on the DAWs but they are really similar, just bigger woofers. The Wilson streak continues...

would be really interesting to learn what other speakers you were considering
I will disclose what speakers I chose later this week. 
On a different note, I had a dealer friend of mine come over last night for a brief moment and he listened to the Merrill 118s with the arc6se versus the full moment set up. He said he " the Merrill and arc " killed the Momentum based on the brief listening session we had. Granted, this was a quick session but his initial impression was " wdf, that's class d playing ? " 
He said it sounded outstanding and the control and speed is far better than the Dag set up. I actually called him out on his comments because he was one of the many people who didn't give class d a chance.  
I will admit, the Merrill and arc 6se is DANGEROUS....
Anyone who listens OBJECTIVELY will reach same conclusion.
On blind video 1 I would have bet the farm that Number 2 was Merrill, and it was. The comments showed 99% picked it over Parasound.

Then on blind video #2 I was not expecting a close battle, but it was. Wasn’t expecting because I assumed you’d leave 118s in the mix. When you revealed then it all made sense. 

Am I surprised that Dag and Parasound are competitive? Not really.

Am I surprised that Merrill destroys Dag in head to head as your dealer observed? Not at all. I’d be surprised if they didn’t.

Now when you unveil the new Gryphon it will lap the Merrill’s just like Colliseum did.
WC,
It appears that the Colosseum is gone, so it is unfortunate that you never did a video A/B with the Merrill.  Please give us your verbal ratings of the Merrill before you move on to other things.  I want to calibrate my rating of Merrill with yours, so I can extrapolate your findings on other amps to see if I should consider them.  Thanks.

Maggies and other inefficient speakers obviously need lots power for very dynamic music.  But at 80 dB, sensible levels with brief 90-100 dB peaks on things like "Keith don't go", 1 to 100 watts (at most) will drive Maggies to satisfactory, natural levels, with better clarity than any dynamic speaker.  You'll see about the new Alexia 2.  I agree about the limitations of Maggies for very dynamic music.  Even the efficient older GTA I heard is better in all respects to any Maggie I have heard, and the newest GTA I will hear soon promises to be even better.
Now that you’ve given your lukewarm review of the Maggies and how they unfortunately fall apart with complicated dynamic music, maybe move on from the planar experiment and get a worthy #2 speaker in behind the Wilsons.

Maggies fun like you say but really without a sub, never had much of a chance to be excellent, and the limitations that you cataloged didn’t even really have to do with lack of bass, they were in addition to that bass deficiency.

Something perhaps like one of those Fyne’s you were talking about. Or Spendor D9.2 ($11k). Or a current Dynaudio, ugly as they are. Or Kef blade or blade 2????
Nope. No Dynaudio for me or splendor. The magnepan will probably be here for a bit longer until I get my "ak47" of an amplifier tomorrow. I want to hear what it can do with the 20.7. 
Dynaudio is no longer of any interest to me. I used to like it but their new stuff just doesn't grab me. I prefer to buy a fyne audio instead 
Finally had time to listen again to the second blind shootout. I thought it was very close, but I’ll give the edge ever so slightly to Number One, the Momentum S250 over the JC1+.

This is actually the very first time I have picked the Dagostino in any of shootouts it has been involved in.
speedbump6,
I have been following you on the interesting Tekton Design Moab thread.  Tell everyone here about what other speakers you compared with the Moab and the flagship Ulf (I'll never remember the full name and its correct spelling, lol).  If I wanted to get ONE dynamic driver speaker with a rating of 9 in everything, I would get the Moab with all Be tweeters for $14K.  Best value would be the standard Moab at $4.5K.

grey9hound,
Do the same for your beloved Double Impact.
thieliste,
Thanks for your elaboration on the Mephisto amp.  As I understand you, the Mephisto gives a combination of the tube sound of the Aries Cerat and the "precision" of the CH Precision.  
@viber6 Well at least it has the meat on the bone of Aries Cerat monos and speed,resolution, sweetness and openess of CH Precision.The Bass control and slam is much better than the other 2 brands.I cannot think of a better all in one package than the Mephisto stereo today.If you don't have the budget for a Mephisto i would definitely look at an Antileon Evo and not the Essence.Just my 2 cents.
In response to the previous posts including Viber6 comments  regarding dynamics- physics dictate the actual physical limitations of a specific driver. A planar magnetic driver used on its own Will inherently only be able to move that only that much air to produce the lower frequencies- this will ultimately pale in comparison to a dynamic woofer. The only way to successfully integrate a dynamic woofer into a planar design used to have an open baffle servodriven woofer system.
This is achieved with an onboard computer which is contained within the servo Amp. Instead of using a slave system where one woofer is connected to the other woofers The better approach would be where each woofer is independently wired with a plus and minus connector to the actual servo  computer.
Byutilizing this type of system you are essentially matching the figure 8 dispersion pattern of the panels and are affectively eliminating the boom and overhang you get with a conventional woofer as the servo system will effectively pull the woofer back as fast as it excurts.
Viber maybe I’m wrong, but thought the ulfers with all be was closer to 19-20k
haha, listen to the essense and pick up his memphisto i bet

As to the question of "why Wilson?" that somebody asked, have you been following the thread and videos? Look at what he always comes back to, and it tells you all you need to know about what he finds to be the best sounding. If he hasn’t had a Wilson and been extolling its virtues over the last year (DAW or Alexia 1), he’s had something else and been lamenting that it wasn’t a Wilson or comparing it to a Wilson. Read between the lines.

Wilson speakers, Gryphon amps (this will be confirmed if the new amp is a Gryphon - if it’s something else then there is no preferred amp brand yet), and Audio Research preamps. Budget category (compared to the deep end of this thread) is Luxman for his preferred (2 of 3 as best all time he’s owned for $$).

That’s the best way to judge what WC thinks is best sound quality -- what he keeps going back to and keeps the longest. In the case of Wilson, he was only able to stand being without one for a couple weeks since the DAWs left, and several times when he talked about the Maggie speakers on the videos during this two week period (or whatever it was) he ended up drawing comparisons to Wilson.
