Michael_moskowich, Tim Aucremann of The Audio Beat http://www.theaudiobeat.com uses a set of MA-1s (with a set of ZEROs) with Sashas. I myself heard the Sashas on MA-1s at Paul Bolin's home. It didn't seem like the speaker was hard to drive at all! So yes, obviously our bigger amps can drive the speaker too. In fact it seems to me that with a set of M-60s and a set of ZEROs you would have plenty of power with Sashas in most rooms.
Here's an article Tim wrote about the MA-1s, scroll down and you will see the Sashas: http://www.theaudiobeat.com/blog/atma_sphere_ma1_mk31_upgrade.htm
Class D, as you can imagine, has made big inroads in the pro-audio and music world. For example Orange now has a class D bass amp that makes 500 watts. Its small and light! It can't keep up with an all-tube Peavey 400-watt bass head though. The Peavey has more punch and bottom end. Mind you we are comparing apples to oranges in a fashion, because its likely that music amps are not built to the same standards as high end stuff. But I find it interesting (and perhaps no coincidence) that the relationship I have observed between class D and tubes in general seems similar to what I have seen in the music field as well.
