I am having some problems with the new P S Audio DirectStream DAC I bought. I am not a audiophile or a computer wiz. I have an old Dell from 2004. I called P S Audio to help with downloading the software and fired up the DAC. Using my USB cable, I was able to listen to WBGO on the net, but I could not listen to WKCR because Windows Player and Real Player gave me error messages ! I need someone who knows audio and PCs !

As you were able to listen to WBGO via your Internet connection and the PS Audio DAC, this suggests your set-up is correct. If you set the PS Audio via USB as your PC's default sound device, are you able to listen to things like YouTube using your Web browser?

Thank you for the link. Amir's measurements aren't that different from Stereophile's, so I am not sure why you imply ours aren't "real."

In addition, when he quotes me as saying in our review that "In many ways PS Audio's DirectStream DAC measures superbly well but..." and says "What? Superbly well? This is is superbly well?" and shows the poor low-frequency linearity graph from my measurements of the review sample with the original firmware, he is ignoring both my "but" and the subsequent measurements at www.stereophile.com/content/new-firmware-measurements, which show that this poor performance had been addressed.
