By the elimination of parasitic effects of excess resistance, capacitance, and inductance, the Signature Interconnects can transmit the musical signal so faithfully that their introduction to your system will be as dramatic as any major component upgrade. Our engineers designed these handcrafted cables to perform at a level higher than was previously thought possible. If you value holographic image focus, clarity and transparency along with a bold dynamic range, you owe it to yourself and your music to upgrade to the MasterBuilt Signature Line Interconnects. Available in single ended RCA or balanced XLR formats, these interconnects are U.S. built with laboratory-grade single-crystal copper along with our proprietary manufacture techniques.
