Concerning this Belmont theatre: As was already mentioned if the room the PRIR was taken is way too big than the room where it is listened to then it will just sound too echoey and silly. And as it seems to me this is a real DCI compliant cinema with a cinema ATMOS processor (Dolby CP850 for example) and I have my doubts thst you can connect the A16 via 16ch analogue to this processor and even if so how do you route the channels and where because there are way more speakers than for a home Atmos system. Won'twork at all I bet. What you need is a good home Atmos setup in a room that's similar in size to your home or an Atmos for home mixing studio, but even there there can be problems like with the msm studios here in Munich if they only can accept digital signals. The Atmos mixing cinema of msm would be ideal, they mix Atmos for home and have a room size similar to a home theatre.
