We did a usb cable shootout about 5 years ago with my audiophile friends. The results we eye opening to say the least. My Luxman dac is very susceptible to changes in usb cables.
We used a WW Starlight Platinum, WW Starlight Red, a Light speed (a $600 cable like the Platinum), an AQ Carbon and a cheap $40 Pangea. All sounded remarkably different with the Platinum sounding the best and the Pangea thin and excruciatingly bright.
