I have always wondered what some of the really high end manufacturers expectations are w/ the really pricey stuff in terms of actual number of units sold.
I suspect some of these products are intended to create or maintain a manufacturer's reputation so they can sell their more reasonably priced offerings & not really intended to sell well themselves. The hope for many of us is that the technology & concepts they develop in creating these outstanding products is that some it can trickle down to more reasonably priced things & more people can benefit from them.
As for the actual price of things, it's all a matter of point of view. I suspect the general public would think that spending even $5K on a pair of loudspeakers is crazy & would not ever consider it but to many here on this forum, that's basically the bare bones starting point for anything decent. The same goes for cars, bicycles, cameras whatever. For some, part of the fun is trying to get close to the sound quality of a top system for a lot less $ using our experience w/ tweeking, set up, room acoustics & used gear as well.
If you work hard for your money, you deserve to spend it anyway you enjoy. If that means donating to charities or buying a $100K sound system, to each their own.
