Guys, here is my scenario. I need to upgrade from my old Sony ES pro logic amp. I am going to buy my new tuner from bestbuy because my friend's brother works there and he said he could get it for me. I narrowed my choices to these. Sony STRDE995 7.1 ( i understand sony's are not that great) Sony STRDE695 6.1 Yamaha 5660 6.1 I am also slightly considering the Pioneer VSX-D812 I have all Northridge Speakers, and a sony dvd player and cd player (not that it matters too much.) The only reason I am even considering the higher end (low end) 7.1 sony is because it is 7.1 and has room for upgrading. Is there any big difference in sound between say a 6.1 setup and a 7.1 setup. I have been out of the hifi game for a while and need some good advice. If there is not big difference I would rather same the cash on the 7th speaker for something else. Not to mention the cash on a 6.1 rather than a 7.1.
