Mike, everything I have right now in BR is either 5.1 DTS HD or DD HD. The LPCM does sound incredible in HD.
I did all my measurments a little above ear level on the couches and am really happy with the results. There is an upgrade on the Denon site for the 4806 that I downloaded to make the Audysey sound even better, but I doubt if I'll feel like moving the unit back out to my computer to implement the upgrade, it already sounds great.
Tonight I'll spend some more time listening and tweeking, I may even take the amp out and see how everything sounds just running off the 4806.
