I currently have a Yamaha 5740 with 60s, VP100, QS4s & STF-2 sub. I bought the receiver used and when it got to my house, the left side was caved in somewhat. I've often wondered if anything internally was damaged and although it seems to work ok, I've never felt 100% comfortable with it. I just bought a Denon 2105 (price seemed to be pretty good) off ebay. The yammie is rated 100wpc & the Denon 90wpc. Not a significant or noticable difference. My question is this?? Does anyone have experience with these 2 receivers? If so, is there a difference in sound quality? My mind is made up that the Denon will sound better but that may just be "mental"!! Thoughts & comments????
