The death of ultra hiend audio

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.

Almost all high-end audio companies either go out of business or become husks of their former selves after being acquired and drastically reorganized. 

Look at Mark Levinson. From legendary 90s powerhouse to zombie brand adrift under Harman’s corporate umbrella.

As far as their ability to repair, they might as well not exist. Try asking them to service Madrigal-era gear.

Let's flip the question around and ask what high end companies are successful and why?  Then we might really learn something.

Its hard to know which brands are truly successful without seeing financials. I would start with brands that have stood the test of time without bottoming out financially or selling to big corporate,  which often results in the brand continuing in name only. 

Accuphase, Pass Labs, and Grado Labs come to mind. Burmester, T+A, and Zellaton are German brands that qualify. Audio Note, Kuzma, Air Tight are other examples and there are many more. One common thread is that all these manufacturers have been known for many years-decades-for building high quality, reliable stuff. As far as I know, they've not succumbed to the temptation of VC buyouts. Each of these companies have a loyal following and concentrate on their core business. They must be doing something right.

If I were the kind of guy who worries about serviceability and is keen to ship gear back to the manufacturer for maintenance, I'd have an all-McIntosh system.
