RF•STOP AC Cable Wrap

Any metal cable acts like an antenna to radiate or absorb RF noise (RF). In particular, an AC power cable can radiate RF with enough energy to degrade the ultimate transparency of a DAC. Proximity, length and construction all play a role but even an impossibly small amount of RF is sufficient to perturb a DACs timing, reference voltage and noise floor — all of it audible.

An audio chain is replete with sources of RF: switch mode power supplies, sources, streamers, network switches, digital tweaks and even amplifiers themselves. When a DAC is interconnected to a powered amplifier, the out-of-band RF from the DAC is modulated to a higher energy by the amplifier power supply and then radiated back to the DAC by the power cable. High-end power cables do typically provide some amount of radiated RF attenuation with a shielded dielectric or with specialized conductor geometry; however, endgame isolation requires a more definitive solution.

RF•STOP™ AC Cable Wrap acts like a Faraday shield over the length of a power cable. Made from heavy metallized layers in a compact woven polyamide fabric, AC Cable Wrap provides full spectrum RF isolation with over 90dB performance. It stops power cables from being antennae so ordinary cables are transformed into sounding better than top-drawer audiophile quality. AC Cable Wrap is sized to fit over standard 1.5" diameter power connectors. A nylon jacket adds durability and Velcro straps with a grip liner secure the ends. 

Add a RF•STOP AC Cable which offers a combination of an integrated full length shielded ferrite cable and RF/EM filters for excellent attenuation of RF noise—more than 40dB above the critical 100MHz frequency range. The combination of AC Cable Wrap over an AC Cable provides the best performance.
