I know the Sony 820 got a great review on these pages, but is it worth that little extra for the Onkyo 606. I know the Sony doesn't upscale but if I'm sending a blue-ray through the Panasonic DMP-BD30 I'm assuming I can get the DVD player to do the upscaling and not the amp. If this is the case is it worth that extra dosh for the Onkyo. Cheers.
