I myself used to have the Denon 4311. My room is also untreated, with horrible reflections and non symmetrical speaker placement. The Denon and XT32 does a very good job with EQ, but you could still localize the speakers. With the R-972 and Trinnov, the speakers are no longer localized. I now have a phantom center, which sounds better than when I had a real one.
What would be the need to keep the Denon? I replaced mine completely, and I have no regrets. The R-972 passes 3D through just fine to my ST50. Are you somehow hoping to use XT32, and then Trinnov on it? It might work, or it might not work at all.
No, I'd use either XT32 or Trinnov. I'm not about to try to overlay them, and create issues with competing priorities.
My speakers are symmetrically placed, so that's not a problem per se; the reflections are more about room configuration (an L-shaped room, where the left side of our listening/living room opens into our dining room), furniture placement, wall surfaces etc. As for the phantom center, I've read some suggestion on this thread that it may work better with Trinnov than some centers, but that's a bridge too far given that I've got a powered center that I'm happy with for music, anyway.
My thought was to keep the Denon because I know everything works with it in the equipment chain, and to avoid complications with setups that might or not work with the Sherwood (and to focus the learning curve on Trinnov rather than HDMI handshake or audio issues with the R-972). But if the poster is correct about there being no A/D conversion on analog multichannel inputs, it's a moot point anyway. This _might_ work with a Denon 4520, which has a Zone Out which can output multichannel HDMI output on one Zone (the Denon 4311 doesn't have multichannel HDMI out AFAIK; I think it downmixes to two-channel if you use the HDMI Monitor Out, even in passthrough mode).
I guess I'll stick with XT32 and look into the treatment route...we've had enough discussion of the shortcomings of Audyssey on the Pro thread and REW on the time domain that it got me thinking of moving into Trinnov. Thanks for the feedback.
