I am in the market for a good home theater receiver. I have a small living room 14' by 20'. I will be using Bose Acoustimass 15 speakers (Please no flame) and will be using it for dvd and for music. I am looking for a receiver with alot of power but also clean sound. I know Yamaha makes an excellent receiver but I am not sure on the Sony. I can get the Yamaha for $669.00 and the Sony for $739.00. Which would you get and why? Thanks in advance for any advice or info you can give.
