I can't see how this little USB sound dongle would be the best anything.
Sure, it's cheap, but the SQ isn't going to be any better than onboard sound. Hell, it might not even be that good.
These people are legit, but ship slowly from HK. Expect 2-3 weeks delivery time.
Might be best in Car Audio? That forum seemed more for speakers, etc.
I totally agree, it's just worth linking in case it's a solution to someone's problem somehow.
