This is an extract from computeraudiophile...
There is much animated discussion on USB cables, and cables in general of course.
Opinions range from:
1. Any USB cable to a DAC sounds the same, even $2 EUR 1.5 ones, so why bother spending more
2. There is no valid technical reason why USB cables sound different, double blind tests confirm that
3. Printer USB cables won't be the same as audio grade USB Cables, so don't use them
4. Different branded USB cables do make a difference
5. I use Brand X USB Cable cause it gives me soundstage/resolution/no smear/great timing/less jitter (select which applies)
6. I can hear the difference between USB Cables
7. USB cables perform better with matched DACS of proportional cost
8. I like Brand X because I like the manufacturer's system sound
9. Brand X cables doesn't produce jitter as much as Brand Y
10. Crosstalk on Brand X cable is minimised between D+ and D- lines, especially the Y type cable
Now all these are opinions, there are (small to large) facts and myths buried in all of them, each one can be analysed until the end of time with really no clear winner or result. In the end, have a read of all the posts, and eventually you will say, heck, I'll just buy Brand X cause it will look good in my system and the price is right.
