Arggh. They are cables carrying an *analog* signal *representing* digital ones and zeros. Little ones and zeros marching happily in pristine formation down a cable is an oversimplified model we have in our minds. Additionally they are *electrical* cables, meaning they can carry electrical and RF noise into the system, including the sensitive digital clock, thus affecting jitter. So yes, they can matter. Fortunately you don't have to spend a lot to find out if the cable makes an audible difference to you. Many people have said good things about Monoprice. Personally, I happen to like the Audioquest Forest USB very much for about $30 US for the .6 meter length. So you can try these or others, and if you don't personally hear any significant difference, return them; or even if you don't send them back, you haven't spent a fortune.
Yea i was debating over the monoprice cables, audioquest forrest or pangea cables. All 3 of them aren't that expensive and won't break my bank. In the end i may pick up both the monoprice and (either the forerst or the pangea) to see if there's an audible difference for myself.
