I have no problem with a company charging the price of an aircraft carrier for their products, because no one is compelled to make those purchases.
If two consenting adults shake hands on a purchase, then it is none of my business why the customer chose to do so. The customer has free will.
Add in that I never listened to that $375,000 MSB DAC, then who am I to judge?
There are people that call any $1,000 interconnect "snake oil", without ever having listened to it in their stereo. I am not about to do the same with that MSB DAC.
I do envy people that have such toys. But I neither begrudge them nor judge them. Person "A" puts it up for sale, and person "B" buys it. That is the free market.
If I was worth $15,000,000,000 then I would audition that DAC. And if it did for my ears what no other DAC could do, then I would buy it. Why not? It would not stop me from purchasing my next yacht, submarine, or Action Comics #1 issue with a top CGC rating.
