Considering these USB cables.

Take a look at the  Pangea Audio Premier XL USB Cable

It should make a considerable improvement in sound quality because it separates signal and power

There is also a similar product from Doukmall on Ebay

I've used the Doukmall and it worked extremely well

Thanks,

As for the cables that separate power, does that matter in my application since power isn't needed? The cable will be for just transferring data, not power.

asahitora - re:...

That may depend on the "geometry" of the cable i.e. how the internal conductors are arranged.

But basically, It would not be an unreasonable assumption

However, if the power conductors are connected to the computer USB supply, there may also be some noise transferred to those conductors that may impact the signal

For example - the antenna on a radio transmitter does not canny any current as such, since is is only connected at one end, but the "noise" on the antenna is considerable.

Some may consider that any such noise to be of no consequence, but since my own experience with building IC's and hearing the difference that seemingly small changes have made to my system - I tend to lean in favour of caution.

Hope that makes sense.

Look at Curious Cable from Australia.  A well known best in class USB cable that should well exceed those mentioned in your list.  Shop used and I think you can stay within your budget for a .8 meter cable.
