In my 'main' sound system, I have components from:
- United States (Schiit Audio -- DAC and monoblock amps)
- Canada (Bryson -- preamplifier)
- South Korea (HiFi Rose network transport)
- England (B&W 803D speakers)
They're all companies that are doing fine, and none of them go for the ultra high-end, except maybe for B&W with the very top of their line.
My own feeling is that ultra high-end audio is kind of like ultra high-end cars; not very many people buy supercars or the like.
But a lot of people buy mid-Lexus cars, and I think a lot of folks buy at the mid-price for audio, as I have done. My most expensive items were the speakers. (I bought floor models at a stereo store in San Francisco that was going out of business and saved some money.)
The trick here, to me, is that my good system (which cost about the same as a Toyota Camry), sounds a million miles better than anything I could have had earlier in life, when it was record players and maybe a cassette player later on. And my current system is also flexible, running Roon with access to Tidal, able to stream in three other rooms of my house.
So the overall audio market looks pretty good to me, but the ultra-high end may always be something of a glamorous invalid. As has been said a number of times here, only the very few can afford those. And whether they're *that* much better is questionable at best.
