Silver Circle Audio uses a no-nonsense approach to everything we design and build. This approach was especially important with our power cords because we understand that power transmission is the very heart of any audio system. Our goal was to provide audiophiles the best quality power transmission at a reasonable price. Towards that end, we developed our Basic Power Cord. At its core is a high-quality 10 AWG copper wire in a Litz-type geometry that is fully shielded. The basic cord is terminated with a Wattgate 5266i male plug and a Wattgate 320 IEC connector. The cable assembly is covered with a braided PET monofilament sleeving.

A major problem in audio system environments is the generation or absorption of electromagnetic interference (EMI) and radio frequency interference (RF). Shielding power cable significantly reduces ambient EMI/RF from entering the audio system through the power cord and reduces any current-born artifact from being propagated. It keeps the bad stuff out and the good stuff in.

People raved about our power cords, but asked for more. First, they asked for an outlet box. The development of the outlet box soon blossomed into a “no holds barred” power conditioner and it quickly became our “pure power one” power conditioner (see Power Conditioner page). The basic cord has been voiced in a very synergistic manner with the pure power one, with termination options selected as appropriate for the gear in use, as the Silver Circle philosophy, manifest in our complete power delivery system, is to provide clean power with no dynamic limitations in a very cost-effective manner for the discerning audiophile.

Next, people asked to have options with respect to the terminations on our power cords. There are far too many combinations and permutations of power connectors to address every one, but the pricing table details most of the combinations available to the discriminating audiophile.

The rationale behind using receptacles of different metals: Different metals, folks have observed, have different sonic signatures. It has also been observed that solid-state systems tend to sound brighter than tube systems. Whether this is reality or perception is immaterial. If a system sounds bright, utilizing receptacles of copper, bronze, brass, or gold can moderate the brightness. If system tends to have a pronounced mid-range or sounds soft, using silver or rhodium-plated receptacles can offset that and punch it up a bit. It is sort of metallurgical tone controls. Silver is extremely detailed and quick - the best conductor. Brass and copper are more laid back. The choices are yours to make. We would be glad to assist you with that decision.

In Vade Forrester's review of the April Music Stello HP100 headphone amp on SoundStage!, he notes that using the Silver circle Audio power cord, he was able to wring an extra octave of bass from the AKG K501 headphones. “No kidding, the bass extended at least an octave lower than I have ever heard it, but retained typical AKG detail and tightness.”

Give one of our power cords a test drive. You may wring that extra iota of performance from your system. We think it is one of the most reasonably priced and most rewarding tweaks you can treat your system to.
