I tried that last year by putting my Dreamcatchers on top of my M80s. I didn't wire them out of phase though. I used 2 side channel ouputs for the Totems and set it up as multi-channel stereo. I have per speaker EQ on my Onk and fooled around with that and channel volume to shape the sound. I also fooled around with the distance settings to add delay. The soundstage was huuuuge but the imaging wasn't great. If I knew what I was doing instead of hacking, I'd bet I could get it to sound pretty good! Hmmmm...I wonder if an Audyssey calibration might fix the imaging.
