If people have 15K as loose change in their pocket and are getting a finer product I don't see why there is any problem. If you have the money there is none.
I worked for a luxury Italian house years ago and women were paying $1,600 for a handbag instead of one for $30 at Penney's and like they say about watches they did the same thing. And if you wanted a truly magnificent handbag that was a work of art you'd pay 26k.
Not to mention the men's Ferrari red alligator driving shoes(literally only for driving or they would wear out in no time) that 10 years ago cost 4k. They truly were astonishing to behold.
I have found that the Lyra Atlas and the Universe Premium when I've heard them are truly works of art.
If you can't afford a painting by Rembrandt you simply don't buy it. And in the world of audio these things are at that kind of level. You might consider the price absurd but then so is the cost of a Rembrandt.
