Since this is a pre-amp having 9.2 outputs for the main room shouldn't be that hard. It's not like they have to fit in 2 more amps for the front heights. Also, having two independantly controlled sub outs for the main room could really help even out the frequency response. If Trinnov could be programmed to account for that type of speaker layout, they could work wonders. I'm lucky enough to have a R972... and although it has been frustrating, there is real potential. Hopefully Outlaw will be able to do a better job implementing the technology. One other note, having experienced Trinnov first hand, having front wides like Audyssey DSX is completely unnecessary, but I think the heights could really add some realism. Having DPLIIz to work from might make that easier, too.
