I’ve tried my TVs built-in speaker, vintage Polk’s 5jr’s and RTA 12’s, and new KEF Q250’s. All three with and without my vintage Polk center channel. The current receiver is a Yamaha TSR-7860. It has room correction. I tried with and without. It doesn’t help at all. Also tried my vintage Marantz quad receiver, and my NAD 3020. Every setup had the same problem of sounding so muddy in the upper mids that dialogue is completely unintelligible and music is unlistenable.
