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 But most of it for sale seems to be pretty new, not older, outdated items.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?
Because PS audio sells lots of stuff that gets people addicted to the sport... and then the elusive chase for the "truth" begins... They also provide 30 day in house trials and they are marketed through Audio Advisor and other catalogs which provide them a larger audience.

It's also pretty good gear for the money! It could be a stepping stone for some but it could also be a final resting place.

Disclaimer: I own their PS Powerplant 300 MwaveII, PS Audio Director 3.5, 3 Powerports, 1 Ultimate Outlet, and now 1 Premier Power. I have owned their interconnects (build quality and packing were amazing, but the bass was bloated compared to my megadollar cables.. but still amazing value for the $$ and I would recommend them to friends.)

Another cool think about the company is upgradablity.. I bought My PS Audio 300 ages ago and was able to upgrade it to their latest spec each time they upgraded the unit. This was a huge value to me since I turn a lot of gear, and probably why it's one of the few pieces I have owned for years.

It's great to see them pushing the USB Dac, and the Phono Preamp that can double as a single unit preamp... Good Values.
I have used their previous range of ic & pc which I have mostly replaced with others. In my set-up they sound too dark & lacking the finer details.
IMO their power filters & power plants are still very good, SQ wise. There was some reliability problems (heat) with the P500 power plant which I then traded in for the P1000.
I have noticed when there is a lot of Benchmark, Wilson or Dynaco equipment for sale, there is a lot of PS Audio for sale too. So the real question is, why is there so much of the other stuff for sale?
Remember it's tax time (and Xmas recovery) so people sell right now and buy after they get their refunds.. that's why tons of stuff is for sale right now.

The reason you you see Wilson stuff for sale right now is because WP7 owners are upgrading to WP8's. Plus I wouldn't say 20 adds for a manufacture is a lot??? There are just as many VR adds and 2-3 times the B&W adds..

I'm glad all this stuff is for sale... drives prices down and allows people to play with a lot more different equipment..

Plus buying off brand (once reviewed products) sometimes means you stuck with a nice piece that you can't unload for 25% of what you paid because no one knows about it.. So these manufactures are a little safer in purchasing as you can resell it and not take to big of a hit...

Once again, all advantages in my book!
