When going out stereo from my Yamaha Tyros to Motion Sound KP-100S, instead of running 2 'separate' mono audio cables from the keyboard to the KP-100S, I'd like to instead, utilize a 'single' 10-12 ft long stereo cable, but one which has 2 'gold end' 1/4" mono plugs (stereo L/R) at each end of the cable. Does 'Monster Cable' or any other cable manufacter make something like this?

Thanks in advance for stereo cable recommendations.
