power amplifiers with ICEpower module

Hi guys, what do you think of the new breed of "digital" amplifiers with the ICEpower modules, I mean sonically. My initial thoughts are neither positive nor negative. I think ICEpowered amplifiers are very clean sonically (very low distortion and coloration), but at the same time they are also a bit cool and lean sounding to me. My current reference is a rather low powered (50 W) class-A Accuphase amplifier.
