Hello Bradz, The Running Springs Haley responds best with the non current limiting, non coloring Running Springs Mongoose ($600). It is intended for this unit. If this cable is a bit out of reach, our customers have found the Cardas Cross ($265) to be a good alternative. Since the Mongoose is Cardas based as well and all of the internal wiring of the Haley is of Cardas Golden Ratio, selecting it's little brother (Cardas Cross) becomes a natural second choice.
