We need to be honest about this cable, because honesty is how we got here.

For 25 years we believed that a good-sounding power cord required ultra-high-purity metallurgy, proper shielding, esoteric dielectric materials, and a price that reflected all of that. That belief was backed by consistent experience — every stock power cord we replaced with an expensive aftermarket cord produced a meaningful improvement. So-called "affordable giant killers" came and went, and none of them stood up to a serious cable over time.

The Sonic Tonic changed that. For the first time in our experience, an inexpensive power cord delivers balance, resolution, presence, and soul to a system's performance in a way that satisfies rather than compromises. We were surprised. We're still a little surprised. We put the Tweek Geek name on it because we mean it.

What It Is

14AWG stranded OFC copper conductors — 2.5 times the copper cross-section of the typical 18AWG cord included in the box with most components. Hospital-grade construction, which means it's built to the same standards as power cords used with sensitive medical equipment. Molded connectors with thick, solid-core gripping surfaces that make and maintain a firm connection with both wall outlets and IEC sockets. An extended ground pin that ensures genuine earth contact rather than a marginal grip.

At 6 feet, DC resistance is 0.015 to 0.016 ohms. It will not limit current delivery to your component.

As a Platform

The Sonic Tonic is what we use as the base cord in The Vessel — our QSA-treated power cord. It's also the cord we include in audition packages when we want customers to compare treated versus untreated. The baseline matters. This one is honest.
