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?

Thank you Audiozen. If I interpret correctly, D-Sonics may be using Abletech when maximizing a design for musicality; conversely, they implement with Pascal when maximizing for power... Is this more/less correct?

Could you qualify the term "much larger", and explain "application"?

Audiozen, which class D amps have you really listened to? Have you actually listened to the D-Sonic and Ncore amps?

Guido..I meant much larger power output then the Ncore set which puts out 1200 watts into 2 ohms and the Abletec puts out 2000 watts into 2 ohms. Application refers to Bruno's non linear design and Bostrom's ZVS (zero voltage switching) and his ADP,(Adaptive pole control)with his loop lineariztion technology. D-Sonic does not favor the Abletec over the Pascal for musicality in their models. As you are aware, Jeff Rowland is using a Pascal amp in his Continuum S2 integrated amplifier. The review on the D-Sonic M2 1500M amp using Pascal, in the September 2012 issue of 6Moons is very positive. Based on the tech sheets provided by Abletec, the maximum damping factor of the ALC 1000M amp used in the D-Sonic M3 600M and 1200S is 4000.

OH... Why does D-Sonic favor Abletech in some models? If Pascal delivers higher power and is equally musical, where is the advantage of AbleTech modules for lower power implementations?

Do Pascal based and AbleTech based amps sound the same except for power rating?

Apologies AudioZen, I am seeking your live opinion. If you have not listened to these amps at all and rely on third party reports, specs, and images of internals only, please let us know.

We have already asked him several times if he has listened to these class D amps or others which he criticizes (i.e. nCore), but it's obvious he hasn't as he always ignores these specific questions. So I don't take his comments on class-d amps (or other topics) seriously.
