I have been privy to the listening sessions that show USB is streets ahead which is why a number of guys out my way, Mike included, have switched to USB exclusively. Mike actually hates computers and it is only the increase in sound quality that compells him to do it.
You simply need any computer and download the drivers from M2Tech. Remember - it uses the M2Tech driver and you download them from here:

A guy I know from the forums here is Aus wanted me to hear his Bryston and Berkeley USB converter - which I did - suffice to say the Bryston was not the winner. I also sent my PDX down to him and he had both for a while. Here is what he wrote:
Tonight I listened to the PDX for about an hour and then put the Bryston on via the Berkeley planning to listen for another hour. After about 20 minutes I put the PDX back on. Wow what a difference.
I have a fellow SNA member coming around on Friday for a comparison but besides that I cant see me playing the Bryston much this side of Monday when the PDX goes to Sydney.
The musicality, depth and warmth of the PDX really brings out the emotion in the music and is just so moreish in comparison. I have been enjoying the PDX but to tell you the truth it wasn't until directly comparing tonight that I released just how musical and emotionally realistic the PDX is over the bryston.
It's going next to a guy in Sydney who contacted me to hear it.
Thanks
Bill
