I'll share brief thoughts on why they went back:
PSB X1T: too similar to current speakers (Image B6)
Denton 80: side-step from PSBs, bloated bass
Denton 85: not for me, treble was too harsh and grating
LS50 Meta: weren't for me, just didn't like their sonic signature
KEF R3 (non meta): honestly liked these but had some amp and car issues at the time and had to send them back, R3 Meta is on my audition list
MA Silver 50 7G: generally liked them, but they sounded really weird with some genres and distractingly so
L82 Classic: decent overall, but too "big" a sound for my space, and the high frequency/treble couldn't get dialed in to balance with the abundant low end
Evo 4.2: hated these
I've also heard in store auditions of some offerings from PSB, Poll, Klipsch. Klipsh Heresy, JBL 4309, Kef R3 Meta, possibly some B&W offerings (generally haven't liked them), Harbeth P3ESR XD, Ascend Acoustics Sierra 2 all on my longlist to narrow down.
