Class D is far enough along you can't stereotype. I heard the Veritas which are Merrill Audio's flagship monoblocks, Taranis big twin brothers, driving 108dB horn speakers and sounding great. I couldn't tell by listening they were Class D, in fact, I was very impressed by the sound I heard, even before the knowledge they were Class D. If any harshness or other negatives existed it surely would have come through on horns that efficient.
I have a Linn, Class V, actually, that weighs a mere 11 lbs, it's rated at 125x5 and has been in faightful service for years in my HT set up. It has driven a 5 speaker Dynaudio speaker set up, and now Revel Performa. So this amp at 11 lbs. has driven some respectable loads under tough conditions as well as any A/B amp. It runs very cool, I keep it in a cabinet, and with autio on/off rarely see it.

There have been 2 or 3 generations of 'd' since my experience with the ASP modules.
No doubt some improvements MUST have been made. And in complete honesty, I was more than satisfied for quite a few years. It was only when I entered the final phases of my setup that I decided to move on. The High Frequency interaction of some sort with my ordinarilly benign-load panels went away with the addition of more traditional amps.
I don't know that 'half bridge' and 'full bridge' designs are not still the basis of these amps.
I'm not, I hope, stereotyping. It is simply physics that you have a given output at a given efficiency resulting in Heat which must be dissipated in some fashion. That the Hypex stuff actually DOES seem to be 'load invariant' IS a big improvement. I'm thinking the output Zobel of my amp WAS the source of my eventual difficulties.
I urge you to read the DataSheets from BOTH Hypex and B&O. The older modules from B&O have time limits AND power limits vs the 'rated' power. The Hypex stuff makes a point of the heat sink / temps being, if not an 'issue', than at least a design point to be considered.
Too much is never enough
I do like some of the technical end of amps but mostly it's the bottomline. The review posted is pretty good and in the near future I'm going to be able to listen to one of Merrill's products in my own system. The comparison to my own Pass amp should be interesting. I'm sure I'll be posting some results.
