I put a simple RCA switch in the setup for now, I may try the GG or some other setup in the near future, it's always fun to tinker around, and I'm guilty as most in this hobby.
I've been playing around with my Oppo 205 through various input/output scenarios. Oppo analog routed through the multi-channel in, HDMI out from the Oppo into the 7703, Oppo Analog into AUX1, Audyssey on, PURE DIRECT, etc. My bottom line, even though the different options sound different, they all sound good. Could I pick them out blind A/B? I have no idea. One thing is I have full range speakers, so if I use the HDMI in I gain access to my dual subs, obviously making a difference, but still comes down to preference. The 7703 still impresses, especially when we watch movies.
Thanks for all the input!
