Wouldn’t go that far. Lol.

Its been a hundred years since you shared room info Matt. If you want help there are folks here willing. Best room upgrade I made recently was new paint. Like a new space. Chesseroo did a similar makeover recently.

If you are just looking to experiment grab stuff on hand and mock it up. Nothing to lose. Atmos is the real deal and kind of leaves 5.1 in the dust. The upmixers are probably the best part, as they apply to any input codec and can be used all the time. (Dolby Surround/DTS Neural X)
