Best Usb A to B cable 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 ??
