High end Class D amps?

Hello madavid0,

     I have the D-Sonic M3-600-M monoblocks, their previous model that I bought about 6 years ago and that utilizes Anaview/Abletec class D power modules.  D-Sonic's current model are the M3A-600-M monoblocks, that utilizes Pascal Pro2 power modules.  These are the same modules that Jeff Rowland chose for his very expensive, but also very positively reviewed, Rowland Continuum 2 integrated amp.
     The owner of D-Sonic, Dennis Deacon, told me years ago that he determined that neither of these modules requires an input buffer and that performance and sound quality didn't improve when he used one, so neither of these models use an input buffer.  He also stated he was forced to source newer class D power modules in the M3 monos model because the prior Anaview/Abletec modules were discontinued.  He said he chose to utilize the newer Pascal Pro2 modules because he thought they offered slightly better sq performance but, overall, they sounded very similar to the older Anaview/Abletec modules. 
     I'd suggest you consider either a used pair of M3 monos, if you can find a pair for sale, or a new pair of theM3A monos.  I can state with certainty that neither of these amps have any of the deficiencies you described.  In fact, I consider their exceptionally smooth and detailed midrange and treble performance, along with presenting a 3-D stereo sound stage illusion with very solid, stable and palpable images, as two of their main attributes. 
     While it's true that these are only two of the numerous positive attributes these amps possess,  they're also two of my favorite and must have attributes in both a peamp and an amp.   I definitely enjoy these qualities far too much in a home audio system to even consider buying any preamp or amp that lacked them. 
    Hopefully, your used Odyssey Kismet amp will also possess these qualities in spades.

Merry  Xmas,

I didn't feel like listening

I think you hit the nail on the head. Some 35 years ago I purchased from a gentleman who after our 1st 2 transactions became a friend who shared what was valuable and I've found to be true, that any gear we have should make us *want* play music more. Everything else (soundstaging, detail, bass, etc etc) is just icing. We freely lent each other gear to try out for a while to see longer term what gave us the *feeling* of "I almost can't wait" to turn on the gear. I've found that *sensing* so to speak, to be the "magic" and can get lost when swapping pieces in search of improvements in resolution, soundstage, bass, etc. After all these years, I still miss the higher noise/hiss Infinity FET preamp I bought from him and traded to someone else that brought a Bedini over.
 FWIW,  They had a well used grand piano that his wife played and how I discovered Maggie Tympanis and ARC gear, I carried in amps too heavy for him lol.

bluorion: "So having a 30-day trial period is nice. W4S offers a 45 day trial---that was another one on my list. The ICs I'll be using with the amp will be Audioquest Big Surs. Do you recommend any particular brand with he D-Sonics? Again, thanks for the thoughtful posts."

Hello bluorion,

     I've read good reviews on the W4S class D amps but have never personally listened to them.  I'm much more comfortable recommending the D-Sonic M3 monos mainly because I've been using them for over 6 years now with 2 different pairs of main speakers, originally with Magnepan 2.7QRs and currently 3.7is, and they've performed exceptionally well on both.  As far as I know, a comparable pair of W4S monoblock amps could perform just as well or even better than the D-Sonics.  You'd probably need to home audition both with your Luxman to find out for certain. 
     If you'd like more than 30 days to audition the D-Sonic amps, I know if you call or email the owner, Dennis Deacon, and request a longer free in-home trial period, he typically extend the time period upon request.
     Your Audioquest Big Surs are high quality cables and should perform very well as ics.  I use custom balanced xlr cables as ics but I believe you'll need to use unbalanced rca cables due to the pre-out connections utilized on your Luxman.  The D-Sonic amps offer a choice of inputs, balanced or unbalanced. with a switch also required to be set appropriately on the back of each amp.

I purchased a Rotel class D five channel amp (RMB-1575) just for curiosity. It’s a very honest 250 wpc @ eight ohm and 500 wpc @ four ohm. I have it connected to my RBH Reference system, a pair of SV-T2, a SV-6200c and two 770 mounted rear wall. Their all four ohm. 
It sounds incredible and can it ever shake the house. It’s a beautiful sounding amp and I’ve enjoyed it also in two channel mode. 
.........however, I replaced it with a Crestron CNAMPX-7x200.....a 100lb block of AB power. This amp is incredible sounding at 350 wpc x seven channels. It’s suprised me that the Rotel was not totally spanked. It’s just so light and cool to touch it seems wrong. 

Class D is the future. Boomers stop bashing it, its a maturing product now. PS Stellar 1200 is sweet, Red Cherry, Merrill at a lot more money would give any amp made today regardless of cost a run. Now a pure tube system and I mean pure tube, with tube rectifiers will have its own unique sound, and many enjoy that.  But solid state vs. Class D well it’s a toss up when you here a well made class D. As I age class D will be for me, no more trying to lift 100 lb. plus amps, in fact if buying today I look more at class D amps then the big solid state Amps or tube amps in the 30-60 lb. range tops.
