Im upgrading from a Sony STR-DH710. I will be buying my new avr from future shop canada. My choice is down to a couple of Pioneers and a couple of Yamahas. Any info or opinions would be appreciated. My main use is music, but my main problem with my current avr, other than lack of power is, a crappy video card. Certain games, listening to music via PS3, and movies will cut out for a few seconds (3 seconds of a black screen during an online boxing match isnt fun). I didnt have this problem with my non hdmi yamaha avr (hdmi from the ps3 to tv, digital optical from ps3 to avr. I played the exact same games and music files and didnt have this issue. Anyone with some knowledge in this area would be helpful. Also I would like to know how a 7.1 avr would act with my 82s and 62s in 5ch music versus biamping them. Im not really concerned about using my center speaker in 5ch I would probally turrn it right down to protect it, it would be useless at the level I turn the towers up and Im not interested in upgrading, for years if at all. Im more interested in how the amp would act towards all four towers.
