Arch, I knew nothing of that Emotiva feature, which doesn't appear to have excited much interest. A quick check showed that instructions here were to use direct radiating rather than surround type wide dispersion speakers. The proposed setup with Mirages doesn't sound promising. Properly located M60s and QS8s really should provide an enveloping soundstage, especially in a mode such as DPLII.

Enjoy the music, not the equipment.
