Bryston 7b3 with Bryston Bit 20?

Haven't bought the Bit 20 because I've decided to run another dedicated 20 amp breaker via 10 awg wire to hospital grade outlet so each Bryston will have it's own ckt (I figure can only help or have no difference. Shouldn't hurt and this is a lot less $$$ than going with the power conditioner (not to say I won't eventually end up with one). Will let you know if I hear an improvement by doubling the AC supply source.

You should ask your question on Audiocircle.com builder section for Bryston. That is where all the Bryston propeller heads hang out, including, VP James Tanner.
