Shunyata Research's Sigma Power Cables

Grant Samuelson of Shunyata Research introduced me to the company's new Sigma series of power cords. Designed to intercept noise at a component's power supply, the Sigmas are available in different models specifically intended for digital, analog, and high-current equipment. Each model has a different ETRON™ filter set that measurably reduces noise for the class of equipment for which it is designed.

Our loudspeaker company uses Shunyata Research products at tradeshows. We have always had great results with their gear. We have not used the new Sigma series yet but if history is a guide, they will be a top performer.
