In a top of the line Accuphase system, the fully balanced output of the source (DA / Phono pre) is connected via XLR to the fully balanced C-3850 and then via XLR to the fully balanced monoblocks
(A-200, A-250, M-6200). At the output of the power amps the phase of one complete amplifier chain per channel (preamp, connections and power amp) is turned 180°.

This eliminates all potentially induced noise and also the common residual noise and distortion of the amplifier and volume control units themselves leading to a cleaner music signal.
Hi, Can you advise, if my preamp a C2450 is connected to the A70 power amp via RCA interconnects, and if my DAC, a Simaudio is connected to my C2450 via XLR interconnects and since the Simaudio component's balanced XLR output is equipped with Pin 2 (+) as opposed to the XLR configuration of the C2450 which is Pin 2 (-), must I still use the phase switch on the preamp to ensure the entire chain is in phase?

Thank you
