I remember running into an audiophile who refused to consider anything about room acoustics. He bought speakers specifically for live, untreated rooms.
Anyone else? What was your solution?
Solution to what? You never met anyone who was happy with the way their room looked and wanted to keep it that way? Or was living with someone who didn't share your obsession with fabric covered fiberglass?
Sounds like your imaginary audiophile already found his solution. Seems to me you're the one unhappy with his solution. But that's your problem. Not his.
Let it go. Problem solved. That's my solution.
