My take is that Wilson and PS Audio sell lots of product. A lot of owners start at the bottom and work their way up the line. Dunno about the others but I think we have to remember that owning audio equipment is a frivolous thing, subject to disposable income that can be fleeting, fads, upgradeitis, needing to sell to buy something completely different, and all manner of other factors. Audio equipment is not quite a necessity. I have a friend who had a rig worth at least a half-million $, including speakers that retailed for $160K, a $100K integrated amp, $65K turntable, and one day he sold it all. I was astonished and asked why. Turns out he was selling it to buy a $340K car. Just because there is a lot of one manufacturer's equipment for sale doesn't necessarily mean there is something wrong with the equipment. It could mean anything. There are a heck of a lot of BMW's for sale but it doesn't mean they are inferior cars. Disclaimer: I own both PS Audio and Wilson--I started with Sophias and sold them to get Watt Puppy 7's, and have some PS power generators and cables.
Why is there so much PS Audio stuff for sale?
There seem to be a ton of PS Audio cabling and components for sale. I know they have a wide product line up, and have been in business quite a while (for this industry). But most of it for sale seems to be pretty new, not older, outdated items. Are they not well regarded? Are they seen as a "stepping stone" manufacturer, where people move on to supposedly bigger and better things? Is their price/performance ratio out of whack? They make so many different items, like all sorts of cables, pre & power amps, DAC's, power conditioners, and tweeks. Is their product line too big, where they're really only good at producing one or a few different things? Is it coincidence? Or something else?
