I read a review of a KEF R3, from a mature experienced listener, and he complained about the dull highs. To paraphrase, he was aware that KEF follows the science in design, but felt that it was still a boring speaker.
Said person brought in a B&W and it “Hurray! Bring back the highs”
My guess is that many well heeled audiophiles were pub/club/rock concert tragics back in golden era of live music, and are now getting on into their 60s or 70s and really do have some high frequency hearing loss.
Certainly I remember back in the 90s, in a showroom, B&W immediately stood out, when auditioned against North American speakers such as those Mirage, Boston Acoustics and Paradigm, & Polk (which all used the NRC for research/design IIRC).
Even when you get to demo your own music, you get to hear “new details”. The salesperson would always remind you that these were “proper English” speakers, and that kinda made it different.
Certainly B&W had a special presence here in Australia, and several times the 6 series were partnered with entry level amplifiers like the NAD.
It got a lot of people into hifi, with subsequent itch/scratch for more bass, better mids, tweaking, swapping in and out sources and amps and cables and rooms and other “careful component matching” advocated by the hi-fi press that is all part of the fun and games of audiophilia /upgraditis.
Down the rabbit hole to the circle of confusion...
I mean, who wants an honest evergreen speaker that last decades?
And how do you sell new products if there’s no upgrade path?
consumerism and capitalism at its very best.
