The biggest problem with audio is that it stagnated a couple of decades ago. The iPod and computer-based music servers are an advance, but nothing else has come about since the CD was introduced. Instead of innovation, we've been subjected to the same things being rehashed over and over and over and trumpeted by the audio rags as the "best ever" when only a slight change has been made from previous models. Further, objectivity has been tossed out the window in favor of profits. Yes, this means the cable "industry." This is nothing more than latter-day alchemy with a helpful dose of mythology and folklore. Sure, around these parts you'll find believers, but this kind of thing causes the vast majority of the population - including the scientific community - to write off audio as hokum and buncombe. If audio wants to be taken seriously again, scientific test results need to be respected and the focus needs to turn to quality and value instead of fashion and status symbols.
The sad thing is that really good audio is available on the cheap. But few manufacturers choose to go this route. Headphones used to be the exception, where you could get good sound for a good price. However, the price range of systems has jumped in the past few years and a number of manufactures have introduced "statement" headphones that often are warmed-over versions of their previous products with leather and aluminum for perceived quality and, of course, fashion because that's what "good" headphones are made of. Aside from pushing prices into the stratospehere, they've also made speakers a value proposition in comparison to the high-status headphones being released. You can get a used pair of speakers (or DIY) and an old receiver for a pretty fair price these days. That's where the real value lies today.
I'll knock off the rant, but I really wish that people would take a look at quality and value instead of fashion and status. You can get an excellent-sounding rig at a fair price today, but people seem fixated on showing off shiny objects and their wealth, whether or not those things actually sound good.
