It's simple marketing. PS Audio heavily advertises their products, and has many authorized online retailers making their catalog very readily available for even the average consumer. Therefore substantially more people buy their product than another lesser known companies offerings. I would venture a guess that the same percentage of PS Audio items are resold as any manufacturers, but because of the larger number of sales, it appears to be way off the norm.
I wouldn't worry about their stuff not performing well, PS Audio is a solid company with some really spectacular products, namely their gain cell amplifiers.
