Don't mean to hijack your thread (looks like you're all set there anyway), but I was wondering -- how do you like the Onkyo 505 receiver? I've done searches, and there's not much feedback on that box here. It's on my short-list (want to avoid all the HDMI upscaling/downscaling mumbo-jumbo of the 605, and just use the receiver for SOUND--imagine that ).
Have you had any AV-synch problems? Crossover work well for adjusting the sub? Any issues with lack of power, or sound quality, etc?
