There was also a glut of PS Audio Perfect Wave DACs for sale a few years ago on Audiogon. Paul McGowan, the head of PS Audio, tends to hype his latest product release, in ways that have undermined his credibility in my book. A year ago, he was claiming the Direct Stream was the best thing since sliced bread. In a recent write up, he wrote that the amp is more important in the audio chain than the DAC. No surprise that PS Audio has a new amp to sell, although he seems to be implying that the Direct Stream now plays second fiddle in his product lineup.
Also, some PS Audio dealers sell their components at deep discounts, so I suspect many owners of new units believe that others who are not aware of these discounts will buy a used unit at a seemingly big discount off the "retail" price. Hence, people think they can buy new and flip for minimal loss, a mistaken perception, in my view. That could explain why so many are for sale.
