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

Owner/Designer Dean Deacon of D-Sonic in Houston in recent months dropped using the B&O ICE amps which he now only uses in the surround channels of his multi-channel home theater amps. He now uses a new Class-D amp in all of his Magnum2 mono and two channel amps which he states is the most technically advanced Class-D amp on the market, called the SOA Class-D core amps. The recent review in 6Moons of his new M2-1500M amp concludes its the closest that Class-D has ever come to tube amps in the upper mid-range and high frequencies.
Anyone bought or heard recently the D-Sonic M2-1500M or the M2-600M? What are your opinions?

The Abletec amps in the D-Sonic products use a modulation technique called phase shift modulation rather than pulse width modulation...interesting..

I'm not a electronics expert. PWM leads to issues in the freq. domain.
I would presume phase modulation might have a similar effect on the phase domain.

derailing the original thread was certainly not my intention. Audiozen, I still used the B&O modules. Thanks again for who alert me on the H2O website problem.

Assessing different technical approaches for Class D seems to me like a technical assessment of ice cream, chocolate versus vanilla. You can read and analyze all you want but won't know what you have exactly until you try it. Often the case with home audio gear. Each company has its own design or marketing focus to help distinguish from the pack. Fun stuff!

Audiozen, I find that to be an unreasonable and thoughtless statement. I have absolutely no connection with Henry or his company, but his business may be doing fine with sales from other sources than Audiogon. There are many major audio companies that do not do any business here, and that fact doesn't mean that they are struggling to survive.
