Yeah, I hear you, and I've no doubt it would change the tonality noticeably. This probably sounds irrational but it's just something I'm reluctant to do. Firstly, the thought of something touching the TV panel (and leaving even more dust!) makes me squirm. Second, as we do watch quite a lot of TV I'd be forever covering and uncovering it. Too much of a pain in the asspidistra

I would consider motorised curtains... one for the room refurb, perhaps.
P.S. am strongly considering acoustic panels either side of the telly, in the corners, where they can hopefully manage some of the complex reflections from front and side wall. Eventually there will be a custom double-shelf for the hi-fi & AV, and I will be moving my turntable wall bracket lower, so there would be room on the left as well as the right
