The one thing no one has mentioned (as far as I have read) is service and support after the sale. Good customer support and service is a hallmark of the high end hifi industry. It has a lot to do with good gear keeping its resale value because people know certain brands are still supported years after the original sale. That service can also include in home setup and adjustments from specially trained individuals. A lot to be said for good customer service. We Americans have grown accustomed to seeking out the best deal so much that now we have to pay for service and support after the sale. Apple, Best Buy, et al have set up a nice side income with their monthly payment plans for warranty support. So for those looking solely at the bottom line point of sale, they prefer to spin the roulette wheel in hopes that their new component never fails. The other problem is that many things we buy today are no longer supported after just a few years.
I'd love to see the look on my grandparents faces if I could have told them that one day people would pay $1500 or more for a telephone and then throw it away in just a couple of years as it becomes obsolete. Not to mention the $17/month extended warranty fee. We have given away so much with respect to customer service.
