New Digital Switching Amplifiers


Anyone had the luxury of comparing any of these fine digital switching amplifiers to eachother or to other high end amplifiers such as Pass, Krell etc?

I own a Bel Canto EVO2-the newest gen2 model-
had it about a year now and all i can say it is
it is very very good.To get the most out of it You need a really good Source and Pre-Amp.I have a Audio Research cd3mkll Cd player and Audio Research PreAmp-Ls16mkll
and with good MIT cable both to speakers and as interconnect in a balanced configuration and Vandersteen 3a Sinature Speaker-the sound is magnificent-some of est I have heard anywhere.
How can someone say that digital amps(actually, some of the Japanese ones I heard in Best Buys gave me a headache also-but I'm thinking Nuforce here{yes, I know they really aren't digital amps}give them a headache, but not notice that cd's give one a headache?
I know with me some do:
"When I had the PS Audio, it gave me headaches like when I listen to CD's from the Cranberries"
