I have a tight living room and would like to upgrade the cheap in-walls that we have been using for years. They were fine for background streaming, but we recently got the old SACD player and turntable hooked up and are wanting higher quality.

Are there many people using the Invisa 525 like this, or do most people use them for Atmos type theater setups?

You can use the Invisa 525 as an in-wall main speaker with no problem. We even make optional square grilles if you prefer that to round grilles.
