I've owned the Soundstage, Sunfire TGII, Bryston SP-1, and Anthem AVM-20, which were all terrific sounding two-channel units in their own ways and ranked in the order listed. But the best sounding two channel I ever got out of a pre/pro was with the EAD Ovation Plus. It doesn't feature analog bypass or component video switching, but I thought I'd give it a nod anyway...
Good luck in your search...
P.S. You might want to check out the Cary Audio pre/pros as well...
