I have to reply to this pretty much anecdotally as I haven't ever had $100,000+ speakers in my house nor in the store. I have heard a fair number at shows but those obviously are not controlled circumstances (room, partnering equipment, setup, choice of music, etc.). I do feel that you can glean a bit from that, though, and my findings fall in line with sunbeamgls: many systems that are musically unimpressive and only the rare one that catches my interest at all.
A couple of stories might illustrate this. In 2013 I went to the CES, even though I am not usually a fan of industry shows (as opposed to those more oriented to actual music lovers). But we were about to move our store and we had just gotten out of both Vienna Acoustics and Sonus faber and were looking for new possibilities. This particular show it seemed like everybody and his brother were introducing $120,000 to $185,000 speakers with over a half-dozen new introductions and many more existing models from companies like Wilson, YG, Nola, Magico, Sonus faber, Raidho, Marten, MBL, Avantgarde, Wisdom, etc. (I'm not sure all these brands had six figure speakers that year, but many did as did others I've forgotten.) What I found interesting is that not one of these systems blew me away. The system that impressed me most at the show was the Vandersteen Model 7. It sold then for the still considerable price of $52,000 but that left it a fraction of the price of the others. Other speakers I found worthwhile were much less expensive like some Dynaudio and DeVore models and the Totem Fire and Metal units. (I tried to get the Totem Element series here for audition but after a wait of several months the Arro was what they managed to bring by.) So I don't have a high opinion of the ultra expensive speakers. (By the way we ended up going with Vandersteen and Dynaudio.)
I also have had direct experience with some Wisdom and Wilson speakers we took in on trade and didn't care for either one. (I don't want to pick names here but one of them, combined with the electronics, SACD player and cables that made up the entire system we took in on trade made one of the worst, most aggressive, nastiest sounds I have ever heard from a system. A number of $30,000 to $50,000 speakers have also passed through that were OK but nothing that got my interest.
As most know I have also displayed at Rocky Mountain Audio Fest in 2014, 2016 and 2017. While I have been mostly busy in my own room I did take an hour or two each time to visit other rooms. Each time most of the really expensive systems were pretty abysmal. I heard two systems in 2017 that were each in the neighborhood of $500,000 to $1,000,000 that literally chased me out of the room they were so bad. I was actually somewhat surprised that a Wilson Benesch/Ypsilon system appeared to be able to make music with digital files. Then they put the vinyl of Kind of Blue on a turntable I didn't recognize and I have rarely heard that much surface noise on a record. Sounded like they had run it over in the parking lot a few times!
It is interesting to note that in 2016, Rafe Arnott, a seasoned reviewer then with Part-Time Audiophile gave our room best sound of show. We were using the $1766 a pair JBL 3677s! The next year, when I also brought the $1453 JBL 4645C subwoofer he found the sound even better. I am currently using a 60 year old pair of Quad ESLs with all original parts except for a power supply rebuild with new diodes. They are performing splendidly while my other pair are being rebuilt to be as good as I can make them - panels all rebuilt by Sheldon Stokes, crossovers rebuilt and wiring reorganized by yours truly and frames tightened up and repainted, OFIL stands with new uprights. Total cost of the Quads when done will be under $2500 (not including my labor or the stands) - not bad for a world class speaker. These will be used at the April Axpona show in Chicago to show off the SINGularity and Slipsik 7.
These same caveats also apply to other components. There are easily over a dozen turntables that run $100,000 or more, before you add the arm and cartridge. Are they better than a fully loaded LP12? I doubt it, but again haven't had them actually in my possession. But the source is the most important part of the system so if these turntables are better than an LP12 then pretty much any system they are connected into should be a better sounding system. In the shows where I have heard them the systems did not impress. And the few $20,000 to $30,000 turntables that have been in my hands did not perform as well as a less expensive LP12 either.
So, no, price has nothing to do with quality and the speaker you mention has never done anything for me. Here is a little review from someone else that I thought stated it pretty well:
