SUPRA EFF-I audio cable

Supra EFF-I - Silverplated tube lead multi-test winning analogue interconnect with high-end aspirations
An unimpeded transmission of even the finest details, at exactly the right moment, is the goal of all cable design. A traditionally designed cable can, however, not achieve sufficient transmission quality. A good interconnect is the result of having addressed the majority of malignant properties in an alternating current circuit. There are a number of ways to do this, where our area of expertis; passive benign cable design is the far most complex. We have to physically layout the leads in a manner that counteracts the resulting physical behaviour of a conductor leading an infinite number of sine waves at an infinite number of levels, while carefully choose proper materials in leads, shields and di-electric.

The skin-effect has a dynamic and clearly audible influence. If we were to transfer just one frequency, the skin-effect would not be any problem. But due to the physical laws, the higher the frequency is, the further out from the conductor center the signal will travel, facing far less crossection conductive area, hence suffering from higher resulting impedance. The end-result will be altered frequency levels and timing compared to the original music signal, thus leaving the reproduction far from transparent.

Suitable for analogue tranmissions both balanced and single-end in mid- to high-end hi-fi applications. Available in a number of standard lengths, as well as custom built. Suitable connectors are Supra PPSL, PPX and the balanced Supra Swift XLR.
