Looking for a portable DAC to use with a netbook. Here is a list of the ones I have looked at so far, let me know what you think is the best option, or another product you know of that might be great, or even a combination of these, like the digital out on one to the digital in on another i.e. Asus U3 > UH6-S.
E-MU series (0202, 0204 etc..) doesn't look to portable
Creative X-Fi HD USB
ASUS U3 Portable DAC (Only Dolby Headphone capable DAC here, kinda nice.)
