As people on this forum know i HAVE alpha 9P POWER AMP , and am enthusiastic about BI-AMPING. Any of you folks tried BI-AMPing with two different amps: eg. NAD 350 for high frequencies and ALPHA 9p for mid/low? Doesnt have to be NAD, i cant get my hands on Arcam gear but here I have choice from Nad, Rotel, and other... Could this combo work and what are disadvantages? Thanks .
