For what it's worth, on those rare occassions when I play a DVD with 'regular' DD or DTS, I do prefer to run the audio via a digital coax directly to the 861v6 rather than via HDIM through HD621. Obviously Bluray goes thru the HD621.

I always decode in the player as I have never been able to hear a difference versus decoding in the processor.

My Kit: 861v8+ID41, 800v4, UHD722, MD600, MS600, MS200, Oppo BDP-203, Genesis 201, Genesis 350 SE, Genesis S4-8 Sub, BG 520i, VTL MB450 II, Krell Showcase 7, Genesis 928 Subs, Danley DTS10 sub, SVS Ultra 16 subs.
