Ultimate Ground – Crystal Edition Ground Cable

The Ultimate Ground Crystal Edition is a high-performance grounding cable designed to provide a direct path between an audio component’s ground connection and the AC safety ground. By helping drain unwanted electrical noise away from sensitive circuitry, it is intended to reveal greater clarity, focus, low-level detail, and spatial definition while preserving the natural character of the music.

Built with 101% IACS pure-copper conductors, air insulation, and Mylar metallic-braid shielding, the Ultimate Ground Crystal Edition is further enhanced with GutWire’s extensive use of natural rare-earth elements and Amethyst. These materials are incorporated into the cable design to help control unwanted electromagnetic and radio-frequency interference, supporting a quieter and more transparent presentation.

The cable is wired exclusively from ground to ground and does not carry the audio signal or mains power. It can be supplied with RCA, XLR, clip, spade, banana, or 3.5 mm component-side terminations, together with Wattgate or region-specific Furutech AC connectors. Individually handcrafted in Canada, the Ultimate Ground Crystal Edition is designed for listeners seeking a more refined and revealing grounding connection for their audio system.
