D class amps with Soundlab speakers

Dob's description matches pretty well to what I hear with the IcePower Bel Canto ref1000m monoblock Class D amps in my system. They seem to work well with most any speaker design it seems though if your speakers are a bottleneck to the sound, you will know it.

"I find that class D works a lot better if they aren't being pushed hard."

PRobaly true with most any SS amp but honestly, I play my BC ref1000m's pretty loud on some relatively inefficient speakers (albeit not electrostats, which are unique electronically) in a decent sized room and I have never detected them being even moderately warm, much less break a sweat. THey seem to handle things without much effort for the most part no matter what. No sign of stress or rough edges in the sound whatsover no matter what. Has not been the case with any other SS amps I have used there, which is one big reason I went to one of the biggest yet most efficient, well reviewed, and tube pre-amp friendly SS amps I could find. I had to stretch a bit to handle the cost but it was worth it.

I have heard other IcePower amps (Rowland) do a similarly nice job with Magnepans however. I can't imagine that a good design that addresses power supply around a stock Icepower amp module like these could not handle just about anything. I might be somewhat more skeptical about some amps that just stick stock Icepower modules in a box but I would expect decent results even there.

My understanding is the efficiency of the high speed switching design of
the class d amp is what enables its compact size and weight including that
of the power supply compared to similar power rated class a or class a/b.

It is really a major technical step forward these days in amp size, weight
power and performance compared to older design approaches. Very
innovative!
