D-SONIC SOA Class-D Core Amps. The best Class-D ?

So my new M3 5 channel amp configured as 1000/1000/600/600/600 watts arrived last week. Even with very few hours it easily bests each amp in a long line of succession in my rack in every conceivable metric... truly a stunning piece.

With over 500 hours of burn-in, my new D-Sonic M3-3800 amplifier is performing at a very high level. Its power is only superseded by its grace with both movies and two channel audio. I'm extremely pleased with its acquisition and expect it to remain in my rack for a long time.

njs, how are you supporting your new amp? I discovered a few months after buying my M2-600 monos that they really respond well to fundamental audiophile setup tweaks more so than any other components I have heard to date. I currently have mine on 3-level isolation platforms with coupling brass footers between the amps and a maple platform supported on decoupling blocks (Mapleshade blocks work best). Also, the amps are very sensitive to emi/rf interference but only when placed too near other emi-sensitive equipment such as power supplies for my preamps. They also seem to really like good ICs and PCs.

The amp was initially placed in an isolation cabinet well away from power supplies and other RF/EMI nasties.

At around 200 hours I upgraded the power cord to a Signal Cable Silver Resolution Reference cable with 20 amp Furutech female termination.

A short while later I put four large Isolate It! sorborthane feet beneath the amp.

Both upgrades clearly made a positive improvement to the amp's slready excellent SQ.

Now that i am approaching a full year with these amps, I have to say that they are extremely responsive to improvements in their own setup as well as upstream in the system. I thought they were really good when I first got them, but they continue to surprise and delight as i have made more than 60 changes to my gear since, mostly in component support. Mine are currently powered by Synergistics Research X2 active master couplers. I get the best results to date using a highly shielded balanced Sonoma Plateau copper cable for the signal. output is through a 4' biwire set of Poeima ii silver ribbons. I have upgraded the connectors on my speakers to cardas CPBP posts that I want to also install on the amps. My amps sit on a pair of round-top granite end tables that I modified with carpet spikes and damping material. Each amp sits on Eden Sound triceratops bear paw brass footers resting on a 15"x2" round maple platform. These are decoupled from the granite top with Maplesade isolation blocks. The amps way only 10# each, with the combined weight of each table/platform/footers is about 35#. It took a lot of listening and experimentation to arrive at the current configuration, but the amps are so revealing that the effort was not overly frustrating.
