My HT is the latest generation Anthem (minus the 8k upgrade I haven't gotten yet). I'm not at a loss for decoding equipment but I just don't really think of music and surround in the same breath.
BTW, I was involved in motion picture sound equipment manufacturing, operations and installations all the way back to the days of Stop Making Sense and Purple Rain, and I have a number of immersive music DVDs and Bluray disks. I just don't really pull them out nearly as often as I stream fro Qobuz or Tidal or listen to Jazz.FM
