Hi thanks for the great information so far.
I'm wondering what the differences would be for me between the 6003 and the 6004. (or even the 5004).
In my case, I use a PS3 as my Blu-ray player, so the only other HDMI input is the cable box. 95% of the movies I watch are blu-ray, so all lossless codecs, but from the PS3 it will be lpcm anyway, I believe. Setup as 5.1, perhaps 7.1 in the future but all of these are capable of that. I have no interest in iphone/ipod, BT capabilities. I plan on using the Audyssey auto-setup features. One of the volume-compression algorithms for night-time movie watching or game playing when the spouse is asleep would be nice also.
I'm of course figuring there will be some deep discounts on the 6003, which will make me consider if the upgrades to the 6004 will be something I would even make use of. There is the 10W/ch of course, but the 100W/ch rating on the 6003 is supposedly conservative anyway, so it should be sufficient. Room is not overly large. Main seating is 7' back from a 67" tv with about 20 feet of open room behind the seating. Room is about 15' wide. So long narrow room with television at one narrow end. Are there any known problems with the x003/x0004 series and the PS3? I typically use the 1080p/24 output to the TV when watching BR discs.
Thanks for any help. I'm frequently discouraged when trying to compare receivers, and the higher end ones just seem to add more features that I won't be using anyway, instead of adding more watts and better sound quality (which is what I'm really interested in.)
