High Speed USB DAC?


A recent article in Stereophile ( July 2011, page 45 ) indicates better sound may be achieved when a USB DAC is on a High Speed USB bus.

I have a PS Audio Digital Link iii. My Mac Mini, using as Music Server, will only recognize the USB Audio Codec ( PS AUDIO DLiii ) on the Non High Speed USB Bus. I've contacted PS Audio and they don't seem to have a clue about this. Anyone know if this device is capable as a High Speed USB device? Am I wasting my time and won't see any realistic sound improvement?

Thanks in advance

Thanks to all for your responses. PS Audio confirmed that the Digital Link iii will not show up as a High Speed Device. They also confirmed that high definition (24 bit 96/192) capable USB DACs will utilize the High speed bus while the DLiii is only 16/48 USB.
