As to high end, I totally understand why many may be enamored by it and as long as it's money one can afford to spend it's ok! I believe in the value to cost ideals though. I do not buy low end junk but I also do not see the value in the diminishing returns that uber high end gives in terms of performance over the multitude of quality gear at lower prices. Of course as audio jewelry of uber high end, well that's another discussion on said value or lack there may be.
The audiophoolery stuff though abounds in this hobby/adventure. I hate the snake oil crap that succeeds in taking money from otherwise regular peoples pockets. I have fallen even slightly for some of this snake oil crap. I've learned my lesson on it all.
I understand. Again, there's some of the uber high end that is head and shoulders sound wise above less expensive units. Not all of it falls into the diminishing returns camp. Is it still overpriced? Probably, but most of audio is that way, and the resale value isn't that great save a few select brands. But, you get what you pay for, imo. On the other hand, I am not adverse to good bang for the buck stuff. That certainly has its merits too. It all boils down to what you are looking for, and what can you get out of it to have a true satisfying emotional and musical experience.
I don't care for snake oil either. I'm not into crazy off the wall tweaks and such. However, I do believe that good quality cables make a difference. That has been a long running debate for at least 30 years now. I base my judgements by my experiments in my own system as well as others. I use excellent cables now, which were not cheap, and I use to have the dirt cheap stuff. And in my opinion, the current cables I now use succeed over the cheaper brands I formerly used. I did hear a noticeable difference; it wasn't subtle.
