Ok, I have PSB 5T's as my mains and I want to bi-amp them. This is what I know so far. I have to disable the internal cross-over in my PSB's. I run a cable from the pre outs of my 777es and run in to an active crossover. The x-over will split into high and low signals, I then run each signal to it's own amp and use the amps to run the high and low of my speakers. So I need 4 amps, or 2 stereo amps. 2 lows, 2 highs. I know there are some amps that are better running the lows and some that are better on the high end. What I need from you guys is some recommendations on which amps i should get. I would like to keep the total price reasonable. Let me know what you guys think!
