MasterBuilt Ultra Line are the apex of audio cables.  Although extremely costly to produce, the performance is well worth the price to music lovers who own the world’s finest audio systems.  Your speaker cable is the final leg in the signal path of your system and can drastically affect the performance of components both in front and behind it,  regardless of quality.  Ultra Line Speaker Cables are the finishing touch in your quest to reproduce a simulation of live music in your home.

MasterBuilt utilizes a proprietary alloy made from precious metals developed by the U.S. aerospace industry to approach as close to a zero resistance state as possible.  The resistance of the Ultra Alloy is so low that a minute voltage pulse would travel through the cable without audible loss.  This trait is critical for use in speaker cables by providing purity of sound, image focus, and an incredible dynamic range.

If you own a world-class audio system and haven’t auditioned the Ultra Line of audio cables, you owe it to yourself to hear how these award winning cables will drastically improve your system.
