Note that price is NOT a factor in this discussion. I'm considering getting rid of my Xbox 360 HD-DVD add-on now that I could get an A2 (D2, whatever) at Costco for that cheap of a price. What do you think? How do the two compare in terms of DVD upscaling as well as Hi-Def playback? The only things that I KNOW will make the A2 more worthwhile for me is the TrueHD decoding (I've preordered the Onkyo 605,) and the fact that it's quieter. Any feedback from people who have experience with both would be greatly appreciated!
