It's an idiotic article. Sure, audiophiles pay a lot for good sound, sure a lot of it is a waste, this can be applied to many areas and products. People pay obscene amounts of money for clothing that is neither very unique or good looking, such as $250 T-shirts with annoying patterns on them. People wear these things to look special to the other special people who know what to look for... nobody else knows or gives a flying screw about the patterns on the shirts signifying mucho wealth. Some will spend any amount on anything that is their passion, whether it is right, wrong, or a waste has nothing to do with it. I despise these sort of articles that portray the obvious as some kind of shocking realization. For instance, a T-shirt from Target works the same as a T-shirt from Sacks 5th Avenue, why is there a price difference? Why do people pay more for Nike's? Why do people pay more for Mercedes? Why do people pay more for a Rolex when a Timex is probably more accurate? WHY WHY WHY?!?!
On another note, I've heard cables change the character of the sound before. I've never heard a proper sounding cable sound better than another proper sounding cable. What I have heard is purposeful coloration induced by cabling at the low end of a cable manufacturer's product line...
It's easy to get carried away with high end audio and there is a lot of BS. But it's not all BS. You do get more the more you pay up to a point, of course, beyond that it's personal preference. I will say with authority that $500-$1000 will get you 90-99% of the way there with a headphone rig. Beyond that it's more personal taste, some will find a sonic signature they just love, good for them, is it "worth it", who knows. Like I said, is a Rolex "worth it"? A ferrari isn't as fast as a lot of cars out there but most car lovers "in the know" will tell you that a ferrari is the primo driving machine. Point is, specs aren't everything, we aren't machines, we have preferences that have to do with personal TASTE, not specifications, that is what makes us human, to each his own as the saying goes.
