I had a Shunyata Research Venom USB for pretty much the same purpose, in terms of sitting distance and direct out from my PC. This was awhile ago, and it worked well. I think it is a 3m length. This is something I don't use anymore but am holding on to it for those one off occasions. If your friend is interested in it, pm me.
Best Usb A to B in $100 to $250 cost zone?
A friend has a pair of the latest Quads ESL2912. He's a semi-pro recordist who uses them for ejoyment and to master/mix his recordings. He likes to record solo acoustic soloists and small groups at 96/24. He sits around 10' away from the Quads to listen. BUT he plays beautiful hi-rez music files from his MacPro into his $3000 high-end DAC via a 4 meter El Cheapo orange-colored usb cable that cost around $15. Which usb A-to-B cable, in the $100 to $250 price zone would you recommend ??
