Currently i have the rtia12's onkyo 707 and onkyo m-282.It sounds good but i would like a little more power and alot more highs.I am looking at the adcom gfa5800, like the ability of biamping,and wanting to know if anyone has this setup and how does it sound and perform.I also have the csi5 for center and fxi6 for surround.
