Edit: Thank you all, have decided to postpone my buy and try hdmi to tv and audio to the AVR for 3D bluray play.
Thank you all for the responses, although after re-reading my original thread, it may have come across a little confusing..
I run Xbox, cable (1080I), and Oppo bluray through my Yamaha, not Pioneer AVR. I have Elemental Designs bookshelfs, which I like a lot and are pretty good IMO.
One reason I bought the Yamaha because I read there is little to no voice lag between AVR sound and television sound.
I would like to know the better of the two mainly regarding picture:
1. Which has the better video processor, Marvell vs HQV Vida, I assume both are better than the Panasonic ST50's.
2. Sound: Which has more open, airy, natural sound? The Yamaha is kinda on the dark side to me, which I'm not a fan of.
Thank you again, I look forward to more opinions.
