The Trinnov is a very sophisticated piece of kit and it is primarily a film processor. If you are not into the whole Dolby Atmos setup and prefer to stick with the 5.1/7.1 music surround setup, then a Meridian 861 can't really be beaten in my opinion. It is wonderfully transparent, very musicality and is easy to use for both film and music.
I've lived with the 861 for several years and the Trinnov Altitude 32 for about a month now. I would consider it a retrograde step to go back to the 861 now. The Trinnov is so precice and articulate in its delivery of both film amd music and the room correction is so effective. Also, you have so much control over the target curve for your listening room.
