I'm a new outlaw member and am looking at the 990/7500 combo. My speakers are Magnepan 1.6"s front, CC3 center and MC1's for surround. I auditioned the Arcam 300 receiver recently and I felt it lacked authority until I bi-amp' the fronts. At that point the Maggie's came alive. My wiring is all in-wall and I do not want the cost and hassle of running new wiring. The 990/7500 sounds as if it might be the ticket. Besides home theater, I truly enjoy great two channel music which alot of prepro's lack at two channel. Any thoughts out there on two channel or driving 4 ohm Magnepan speakers
