I have a Storm III and have connected it to several amps using the Neutrik cable. This method is much better in my experience than using RCA interconnet to pre-outs.
The correct way to connect it is Red wire to the Right + terminal on your amp, Yellow Wire to the Left +, and Black Wire to either right or left - terminal. If your amp is a fully balanced design then the black wire needs to be connected to a ground point on the amp chassis, not the speaker - (on my Ayre amp I connected it to a chassis screw).
I'm not familiar with your amp, is there something special about it that causes you to thin + and - terminals should be reversed in the wiring scheme?
