I am looking to upgrade my HT, presently I have a Bose Lifestyle 12 (yes you heard it right I have a Bose) and am thinking of the following
Front R/L Rti8
Centre Csi6
Back Surround FXi A6
Side Surround RC65i
Sub PB1000 or LVR12

The other option I have is to go with CMT340 in lieu of Rti8.

Any advice from you folks is appreciated. Also based on the above configuration I will need some suggestion on the AVR. I was currently looking at Yamaha RX-V675 and was wondering if this AVR is good enough to power this setup.

My room size is 25' x 13' with 8' ceiling and will be used exclusively for watching movies.
