So the wife got me an adcom gfa 545 for Christmas. So Now I have the 545 powering the front left and right and the gfa 535 powering the center. Damn this thing is in mint shape, I know I say that allot when I buy used gear, but this thing looks like it just came off the showroom floor!!!! I am really digging these adcom's right now, I know they are not the best amps out there and that they are older, but damn does it make a big improvement on the sound!!! I know I have said it before but those of you not running separates need to start doing so, the highs,mids, and dynamics are just so much better. Here is a couple pic's I robbed from google.
