Surround speaker setup: disc player or processor?

My Ayre DX-5 DSD and Bryston SP3 processor both have menus for setting speaker size, distance, level, etc.  Which should I use?  If it's relevant to the question:  For surround the disc player sends 7.1 LPCM via HDMI to the processor.  The SP3 returns stereo to an Ayre KX-5 by-pass input, and sends surround to a pair of NAD C268 amps.  A passive Marchand high-pass fixed at 80 Hz 24 dB/octave sits between the KX-5 and VX-5 amp; an output from the KX-5 goes through a Velodyne bass manager set at 80 Hz 24 dB/octave to a pair of HGS-15 subs.  The SP3 is not used for stereo.
