I have a pair of Rti A9s that I am thinking about Bi-amping. I am currently running them off of a HK 635 @ 75W rms. I also have a CSi A6 center on the HK. I just purchased a HK PA 2000 amp that runs 100W rms x2. From some of the reviews I have read about the PA 2000, It may run closer to 150W rms.
I am trying to decide if I should run the Rti A9 highs off of the receiver and the lows off of the PA 2000 or should I just run the A9s full range from the 2000. Does anyone have any ideas about which would sound better? What about the center channel? Will the receiver's power still give me a good sound stage?
