I was disgusted that the S&V review didn't discuss the Bryston SP 1.7 - I own one and feel it blows away the Parasound (and I ever was impressed by any of my friend's anthem stuff). Haven't heard the Krell, so I can't comment there... but having made the move from a 1055 myself, well, I don't think it can get much better than the Bryston - 20yr warranty, 2ch bypass, absolute purist piece (no video switching!!). Yeah there's obviously a lot better straight-up 2ch stuff out there, but this is the best sounding (for music) HT pre-pro I've ever encountered.
