The reason is that, for example, you can buy a Moon 891/861 combo for 1/3 or less than the price of some of these uber high end brands and get excellent sound. The sound of these $100k plus set ups is not likely 2x to 3x or more better. The customers willing to pay multiples higher for improvements is limited. There are also fewer dealers and opportunities to actually audition the uber high end equipment, and it is hard to spend multiples of money relying solely on good reviews from respected publications. Even more concerning is that one of these companies goes out of business and there is no ability to repair or warranty.
The death of ultra hiend audio
Verity and DarTzeel last year, now MBL, ultra high end audio manufacturers are facing their demise and they have nobody but themselves to blame. What do these companies have in common: too much investment in creating the very best and when that fails raising their prices bottom up to recover their losses and inevitably charging 2x what the same product cost just a few years ago. Ego, greed and poor management can only result in one thing!
