Its architecture keeps signal and power delivery completely separate: two 6N pure silver conductors with PTFE dielectric handle the primary signal path, while separate medium-gauge silver AirStrings handle DC power delivery, isolated from the data lines. It's built on the same extended-duration high-voltage conditioning process as the rest of the SRX XL line. Its shield can be star-grounded to a Synergistic Research \u003ca href=\"\/products\/synergistic-research-ground-block\"\u003eGround Block\u003c\/a\u003e or \u003ca href=\"\/products\/synergistic-research-active-ground-block-sx\"\u003eActive Ground Block\u003c\/a\u003e (sold separately) for a further reduction in noise floor. Owners with a complete loom of SRX series cables can trade in for up to 70% credit toward SRX XL through the Lifetime Passport Protection Program.
