Overview

Radio frequency interference is now universally regarded to be a major problem in high quality audio replay. As all cables, generally speaking, act as antenna and attract RFI it was vital to provide an affordable solution to this problem whilst maintaining neutrality within the cable design.

The Premium, Elite, Optimum and Supreme offer a sensible solution to this problem and are designed to work with our more sophisticated filtering products without adding characteristics of their own, a problem that is often overlooked within mains cable design.

We chose not to offer a platting solution, although this is a wise choice for RFI rejection capacitance is often built up within the cable as a by product, in our designs we wanted to not only provide a good quality link to our products from the mains supply and to equipment coupled to our equipment but also provide a link that did not alter the sonic characterises of the hardware. Therefore our cables offer a no-nonsense solution. Three high-grade cores of annealed Oxygen Free Copper conductors are encased in a highly flexible PVC inner sheath, this is then surrounded by a braided screen, this earthed screen forms an active RF shield around the inner cores. The effect is a reduction in the background mush within the system, producing a more open airy sound with a greater sense of high frequency detail. The cable is terminated with high quality connectors to ensure long-term reliability and performance.

Premium

High quality 16 amp rated OFC cable suitable for use with all components. RFI and EMI shielded whilst being fitted with a high quality mains plug and a conventional IEC connector.

Elite

The IsoTek Elite mains cables provide a solution without sacrifice to the audio signal. Constructed from three cores of annealed Oxygen Free Copper conductors within a highly flexible PVC inner sheath and surrounded by a braided screen, this screen forms an active RF shield around the inner cores. The effect is a reduction in the background mush within the system, producing a more open airy sound with a greater sense of high frequency detail. Rated at 16A makes this cable ideal for all components especially power amplifiers, power supplies and of course mains conditioning devices. The Elite is also fitted with an IsoTek high quality IEC connector.

Optimum

The Optimum uses the same high grade Oxygen Free Copper as the Elite, but with larger conductors rated at 20A. This makes it ideal for use with amplifiers and active speakers and anything else which may draw a large amount of current. The Optimum uses a high quality copper plug and the IsoTek high quality IEC connector.

Supreme

Using the same cable as the Optimum, the Supreme is even better for high current products as it uses a high quality gold Furutech 3 pin plug, with a IsoTek high quality IEC connector. Available in the UK only.
