Regarding people's comments about Focal, I heard a pair of Focal Kantas (no. 3 I think) at the Tampa show in February and thought they sounded pretty good--not overly bright for sure, although I expect they wouldn't measure perfectly flat either. This is the only pair of Focal speakers I've ever heard so I have no reason to doubt anyone's observations, just saying that this particular pair didn't seem extra bright.
I've heard lots of Goldenear Triton speakers (5, 2+, 1, 1.R, and Ref) at various times, locations, setups, and with familiar music...I don't have a problem with them and I can certainly see why people would like them so much. They sound pretty natural to me. The top octave in all the graphs looks terrible, but, although I can hear up to 15-16 kHz, I can't differentiate the rough top octave when listening to music--maybe I could with test tones or something.
Expensive speakers that I thought were disappointing include: Muraudio SP1, two sets of Martin Logans including a pair of Neoliths, and Von Schweikert Ultra 11 (I did like the Ultra 55 though). I'm willing to believe it's because they were in hotel rooms, not set up properly, or because of my seating location. For example, I thought the Spendor A7s at the 2020 Tampa show sounded atrocious, but I thought the same speakers at the 2019 show sounded excellent.
