I surely don’t mean offense
@MKR , but that’s not sampling HT, that’s sampling soundtrack music.
Those music sources were just as likely studio down-mixed to stereo from whatever multi-channel format the movie was distributed with, as they were studio up-mixed for multi-channel theater from an original stereo recording. It would depend on each individual original recording, I guess.
In either case, a soundtrack music source won’t have the complexity of music x special effects taxing drivers simultaneously. Those might be important differences, especially if you prioritize dynamics.
What would the plans for center / surrounds be with some of the more recent even-less-mainstream competition be? That was discussed some time ago, but the playing field seems to have changed a bit during the interim.
Mind you I’m personally satisfied to have everything HT crudely down-mixed in-house to stereo (supported by stereo subs). Multi-channel is more of a room-layout commitment than I want, so I’ve got nothing but support for a nice pair of speakers
doing emulating full “HT” duty. Could be an issue for those of ya’s wanting the ceiling/back wall spatial cues of 5, 7, 9+ channels, though. The Trinnov’s you spoke well of sure have the ability to pull more sophisticated duties than managing L / R stereo. Seems worth considering.
