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?

Anyone have the new M3 D-Sonic or know what the difference is?

So I asked Dennis about the difference an all he said was the the 3 is "newer technology". And that the 2 was ICE. He noted that the later 2's are also "newer technology". So now the 3's are officially not ICE, but what are they?

As I already indicated..D-Sonic is using Pascal amplifiers in their newest models as well as Jeff Rowland using Pascal
in his new mono blocks and his new Continuum S2 integrated. So much going on this year with Class D including the anticipated Bel Canto Class D amp without switching transistors which has an original DC power supply. In the works for two years. First of its kind.

To be more specific, Rowland makes the new M525stereo: a 250W stereo amp bridgeable to 1000W mono operations. The device is based on Pascal power conversion modules with PFC integrated in the power supply... M525 has just started to ship. Continuum S2 is based on different Pascal modules, and is not shipping yet.

To add to the extant class D lore,

I have written a review of the Merrill Veritas monoblocks for Positive Feedback on issue No. 68:

http://positive-feedback.com/Issue68/merrill_audio.htm

Once the amps were properly broken in with 1,000 hours of active operations, I did not detect any musical bandwidth limitations, nor any stereotypical class D artifacts with Veritas... I could hear only music.

The examination of further examples of new class D amps should confirm or disprove my hypothesis of class D designs having now grown up into general musical adulthood.
