Gshepardbuster, whichever Krells were about 18k a pair in '07 would most probably be a step forward, though I don't know how big a step. I listened to them extensively in what were then very familiar circumstances (i.e. I sold them and I sold McIntosh, among other stuff). The McIntosh amps I had to compare the Krell with were about 1/2 the price (500w monos I think) and were not as transparent or fast. The Bel Canto Evo 200.2 which I compared with the Mac and the Krell came out in the middle, closer to the Mac. Of course, the big Mac amps you speak about are another matter. I've not heard them. I love the company, love the resale value, and love to support a domestic manufacturer, so it would be great if Mac is what I wind up with. Sound quality is still, however, my ultimate criteria. I've just never heard a Mac amp that's as fast as music really sounds. I'm totally open to the possibility, however.
