I'd like any opinons on the Onkyo TX-DS595 vs. the Yamaha RX-V520 (HTR-5450) or the Denon 1602. I know that the Onkyo & Denon have Dolby Pro Logic II whereas the Yamaha does not. Supposedly the new Yamaha RX-V530 has DPL II, but I can't find anything about it on the Yamaha web site. Other than that, they seem to match up pretty well. Things important to me are assignable optical (& coaxial) ins as well as at least 3 S-Video inupts. Any opinions from current owners of each model? Thanks!!
