[I hope it's okay to dig this topic out again, even if it's only 2-3 months old.]
This video makes me contemplate. Isn't owning insanely expensive gear "dangerous"? In a twisted way, once you reach a certain level and have gotten used to it, you will find that anything below that sounds like crap.
I remember when I stocked up from my 10€ headphones to 50€ ones and assumed it was the best sound there could ever be, until I bought 250€ headphones and suddenly realized that my 50€ are actually pretty damn lackluster as well. From where I stand right now, I cannot go back down again, because now I know what I'm "missing out" with my cheap headphones. So if my 250€ headphones were ever going to break, I simply couldn't pick anything that plays in leagues below it.
If I were to listen to STAX for a couple weeks now, like it was done in this video, wouldn't it just leave me craving to hear that incredible sound again? Instead I would be sitting here with headphones that cost a small fraction of the 10,000€+ one has to pay for STAX plus amp, knowing full well that I'm deluding myself into thinking my 250€ headphones are good.
To put it in one sentence: Can you get addicted to expensive HiFi gear?
