Twilo,
I own a White Audio Labs A-100. It is superior to any other solid state amp which I have owned(Muse,Belles,Musical Design). The A-100 is rated at 100wpc. I believe that it runs pure class A to about 70watts. The other amps which I have used were all rated at about the same power, however the White has excellent bass control and slam that easily betters the others. The White also throws up a three dimensional soundstage and reproduces detail without harshness. My A100 also runs relatively cool, just warm to the touch. These views are, of course, just my subjective opinion.
(Randy White is the guy to contact @www.llanodesign , he is extremely helpful.)

John
