Thanks for the info, TDA - I look forward to hearing what you think once you get the amp in and the 990 has the chance to really stretch its legs.

Interesting comment about the weight. I remember the 990 being pretty hefty for a processor, but it's been over two years since I moved my main amp at all. The reduction in power supply demands and the elimination of those big honkin' heat sinks does make for an effective diet compared to a receiver. It reminds me of my thoughts when I unpacked my monoblocks - the M200's seem so small, but they're nothing but power supply and heat sink and the weight startled me at the time.
