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?

Henry..last time on the subject..want to stay focused on D-Sonic/Abletec. Discovered that IceH2oaudio.com ISP is hosted by Covad Communications which was bought out by Megapath Communications. Called Megapath and they do not have IceH2oaudio in their system and informed me that its a domain name that is available to purchase. The current location for IceH2oaudio.com is in Lutherville Timonium, Maryland. Ring a bell?..

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!
