15' is not a length that would be prone to pickup of noise or hum. I would check carefully that you actually need to run differential before doing so. In most instances where there is pickup of hum, simply re-routing the cables takes care of it. Most of my interconnects are over 20 feet in a tri-amped configuration and I have no problems whatsoever with noise or hum pickup.
