Haha "evolving" is putting it nicely, but I think I can finally stop fussing about speakers and TV's and just enjoy the setup. Also happy to report that my marriage is still going strong.

ARC was set to only apply corrections below 5000Hz, but I can set that limit to whatever I'd like (need to play with it). I've previously tried setting it to 500Hz and below, but found that movies sounded less detailed.
