The Hook Up YouTube channel has a ton of awesome non sponsored reviews of tech that you might be interested in. Projectors, sound equipment, etc. I’ve honestly never seen better consumer review content.

Personally I don’t care for home theater so often I skip videos about projectors, but there’s a ton of stuff there that might help you make some decisions - at the very least you’ll walk away better educated about what makes a quality piece of kit.
