That's almost 1150.00 Right now I am using my old Audion 2 way SS crossover on the Altecs with the Chip amps. I know you were interested in the amps so let me say they sound damned good this way. I don't see why you could'nt build a SS xover, Is there a scematic on the Elliots audio site, I believe so, and I think he provides a PC board but I am not sure on that. Steve Bench still offers the 6922 boards, I just checked. Boy these chip amps are fun.
