For the last week or so I have been driving my W/P Sasha with a lil Krell S300i integrated. The amp sounds GREAT with those speakers, absoulutely no problem with driving them to high SPL.
I just though I would share this piece of info in this thread, since so many ppl (me included) have worried that W/P Sasha would be very difficoult to drive. I guess they are not the easiest load, but they are not THAT hard to drive as specs may suggest. If $2500 integrated can drive them without problems, then almost any HQ poweramp should be up to the task.
BTW - S300i is a great lil amp. MUCH better than the 400xi it replaced, very un-Krell like. If you need an integrated for your office/second system, this one is worth checking out !
