Hiya guys, I have the chance to pick this speakers up for 850( 12inch woofer, 4 sattelites and a center). They were a demo unit in an electronics store. Is this a good deal, or would it be smarter to go witht he newer model 9000 (plastic vs aluminum). The reciever I plan on driving them with is a dennon 3802. Any comments would be greatly appreciated!!!!
