How does the Rotel RSP-1066 sound?

I'm curious as to how well this processor stacks up against other more expensive pre-pro's like B&K's ref 30/50, Classe's SSP-30 MkII, Krell Showcase, Sunfire III, etc.
My first interest is in direct 2 ch. quality and then surround processing and ergonomics.

Thanks,
Martin
