We should get some of those home theatre / speaker / audio communities going.

If there aren’t any yet, maybe a big one to cover a lot of areas until we have a need for smaller ones?

Stupid question- what’s the best way to play these to ensure I’m getting the raw audio signal? I have a Fire stick

If you also need test videos, Demolandia is another great resource. However, their site is very slow, so you might want to use a download manager.
