Synergistic Research HD SX Grounding Cable Extensions

Synergistic Research HD SX Grounding Cable Extensions

HD SX Grounding Cable Extensions let you lengthen an existing HD SX Grounding Cable run without stepping down to lower-grade wire, useful when a ground block is positioned farther from a component, rack, or turntable than the standard cable length allows. They're built to the same HD SX standard: single-crystal, six-nines pure silver AirString conductor, UEF-treated Matrix Shield, and three-stage high-voltage conditioning shared with Synergistic Research's flagship SRX cables. As an authorized Synergistic Research dealer in Toronto, Canada, Vinyl Sound can help you plan cable runs for larger systems or rooms.

HD SX Grounding Cable Extensions FAQ

When do I need an extension instead of a longer cable?
If you already own an HD SX Grounding Cable and only need additional length — for example, after rearranging a rack or adding a turntable farther from your ground block — an extension avoids replacing the original cable.
