Whatever it is it sounds AWESOME! on the HTP-1 thread at AVS we have a lot us owners that love that upmixer. Also on the Marantz AV-10 thread as well.My experience is the same as Gene's. Auro D is basically multichannel stereo. Both he and I can cut out amps without unplugging anything, so we can tell what these upmixer really do. The Dolby DD up mixer is the only one that actually does what it says on the tin.
I do love the Dolby upmixer as well for both music and movies.
For music I switch between Auro and Dolby just depends on my mood
