Will a quality USB cable make a difference....

Digital is digital. 1's are 1's and 0's are 0's.
It will work or it wont, if there is a poor connection you will hear it. Don't be an AudioPhool.

@Docks, I'm gonna quote Judge Belvin Perry (Casey Anthony trial) regarding your 6-14-11 post:

"What we don't know is a wide universe of things we don't know."

If you don't have the experience (aka experiential knowledge), Docks, why post a comment other than to exercise your keyboard and typing digits ("digital is digital")?

Get the audio experience of trying several HQ USB cables on a HQ system, and get back to us, & don't forget...

I tried a us30 cable and a us150 USB cable. Sad to say, the difference is very very noticeable. The more pricey cable is fuller, more 3 dimensional and just more flesh out midrange.
I bought the us150 cable and couldn't go back.

which 150 dollar usb cable is that? Pls share.

Thanks for going the extra little bit to help our economy (or your ecomony, they all need help). That's all you did unless you forgot to mention it was a blind test and you picked the correct cable 19 or 20 times out of 20 attempts to make it statistically valid. Sighted tests don't mean diddly. Do a little research on how what your brain can and can't do with audio frequencies, especially after a second or so of hearing something.
