Anything wrong with PS Audio DirectStream DACs?

Why are there that many for sale? Because PS Audio sold 10-100X the amount of DACs as the other players.

One thing to note about the DirectStream is that it's very sensitive to USB input quality, which is odd for such a expensive DAC... On Windows, you pretty much have to use jplay 6 and then it will sound like the reviewer's rating, it's amazing.

Without jplay it actually sounds odd.

Also, the DS really need a data only USB cable or a USB card that can cut off the power.
