Anyone With A Class 'D' Amp Play A 4 or 2 Ohm Speaker?

I’m happily using ICEpower based monoblocks on a pair of 4 ohm rated floorstanders with 12" woofers. I drive these hard, without a hiccup from my amps. However, they are a traditional design, not electrostats.

I’d listen to Erik, he tends to know of what he speaks.
