Ok...any of you guys go from 6.1 or 7.1 back to 5.1? The reason I'm asking is I currently have a 7.1 set-up, and I do like the way it sounds I suppose, I just don't really notice all that much difference between reg. 5.1 vs. the 7.1 configuration. Everything is calibrated correctly with an SPL meter and my living room is fairly optimal for the 7.1 configuration (for a living room). I have played with just using it on EX and ES DVD's...and also just running it in matrix mode for all 5.1 movies. I just can't tell all that much difference. My side surrounds image REALLY well (monopoles) behind the listener/viewers. I guess I can leave them back there for coolness factor etc....but I have been thinking of using my pair of rear surrounds for a very small 2-channel set up in my home office just for playing vinyl. Anyway...those of you who have 7.1 or 6.1 one...what do YOU think???
