You hit that one on the head , I was using a Onkyo PR-SC5508 and a XPA-5 to drive my setup then last week I picked up a TX-SR806 used for my garage , well I wanted to test it out to make it worked so I pulled the 5508 and XPA-5 .Guess what I was in shock I could not tell any diffrence in sound
or power using the 130w Onkyo 806 So to make this story short I bought a TX-NR809 Last night for 700.00 shipped and Im going to sell my 5508 and
XPA-5 for my size room its just right . I also watched a movie last night and never even thought twice about keeping the 5508 and XPA-5 2400.00 VS 700.00
