I have ran in the new USB cable for over 500 hours on my desktop to my V-DAC. The moment I plugged into the new setup, you can really tell the difference. The human voices sounds more natural while the positioning of the music is more accurate. I would say this USB cable is doing a great job.
Honestly, I have not considered AMD at all. There are 3 reasons why I picked the Samsung NF210:
1. I have been the first generation Atom user since the EeePC 901 and loved the music from it. The new dual core N550 @ 1.5 Ghz will provide an even better audio performance compare with the 1.66 GHz Atom.
2. I previously owned AMD products and they all gave me loads of headaches.
3. I have became a Samsung fan since I got my Galaxy S I9000.
