Maybe I am the only dissenting vote but I like 7.1. It however didn't cost me for extra speakers as I am using some old mission bookshelves as the back surround speakers. I find they seem to fill in the back area quite nicely. YMMV.

I'm interested in this discussion.

Is there any REAL compelling rationale for 7.1 over 6.1?

Discuss.

Maret, if you have enough room behind your listening position for a back surround effect to develop(say at least 4')then a 7.1 speaker setup can be used with advantage. This applies to both 2 channel and 5 channel source material; processing such as DPLII extracts natural ambience present(in varying degrees)in 2 channel material and steers it to the side surrounds and also the part which should be imaged in back is steered in "stereo" to the back surround speakers. with 5 channel DVDs processing such as DPLIIx leaves the front channels unaffected, but processes the side channels to extract information which should be imaged in back and again steers it there in "stereo". Use of two rather than one back surround is suggested both to take advantage of a possible left back/right back difference and to avoid a psychoacoustic "reversal" effect in which a center back sound is instead heard as being center front.

I have some old speakers, it can't hurt to give them a try. I have a couple cheap bookshelf speakers and 2 Bose satellites. Which do you think would be better to use.
Thanks.

Maret, to avoid disgracing myself, I suppose that I have to suggest the cheap bookshelves.

I think this is the biggest reason 7.1 came to be over 6.1. Your ears are designed with better sensitivity toward the front. When we have more content with the rear surround channels it will become more commonplace and certainly of greater value.

Ahh, but with the Q series the sound stays in the rear, not thrust out over you eliminating that effect.

Depending on the source you are playing, rear surrounds can be VERY enveloping. You don't need much distance behind you either. I've only got around four feet.

Seeing how you have a wonderful AVR, I wouldn't hesitate going with 7.1.
