Class D with low-end drive/slam


Anyone know of a Class D power amp, for around $1500-$2000 on the used market, with great low end?

Looking for forceful drive and slam. "Boom boom," as some may say.

More wattage/current the better.

What about the Virtue Audio ICEblocks? They are mono blocks containing a tube buffer and the ICE circuit. Anyone heard them?
