At some point I'll be experimenting with it. Wired the media for the extra two speakers (VOG and center height) and plan to use all 15 outputs of the 8805.

The diagram in the 8805 manual is very helpful, as is understanding all 3 format speaker location specs (which seem to vary a bit from depending on where your getting your info from). Depending on the dimensions of your room/listening area this can be a challenge.
