My BDP-105 connection path: 7.1 analog outputs (using dedicated FR/FL) -> Marantz AV8801 -> Outlaw 7500 -> Revel Salons.
I can tell you the sound is different than via the HDMI outs/
I prefer the analog outs for Music and it I just leave it that way for movies too and it sounds great.
There are many that find no difference so this is a truly a case of YMMV.
Rich do you have to adjust the Sub-woofer level up? This is the one adjustment I need to make when I choose to go the analog route for bluray movies.
