How much of an improvement would an 805 be compared to my current onkyo tx-sr574? I don't need to crank the receiver to extreme levels since my room is very small (9x9 bedroom for now until i get out of college). I currently have 2 Polk Audio RTi12's as my front left and right, and I will be getting my center and rear surrounds in the future. Besides connectivity, would there be a big difference in sound quality compared to my current 574?
I forgot to mention that the 805 is going for $600. Since I work at an electronics store, I can tell all my other associates to not sell it so the price can drop a little more (since its sitting in the backstock) but I am afraid my supervisor will find out and put it out on the floor and someone will buy it. So what would you guys say would be a good deal on that 805?
