Cable Design

Obtaining “Acoustically invisible” audio interconnection cable has, in one sense, become the Holy Grail for the high end audio consumer. As other audio components (amplifiers, preamplifiers, CD players, speakers, etc.) have rapidly evolved; they have continued to be interconnected by cables with similar, and in some cases identical, geometries to their 1940’s era ancestors. EnKlein seeks to change that trend through a scientific approach utilizing our engineers experience with signal transmission and power conduction. We strive to create cables that are “acoustically invisible”. All of our cables are handmade in the United States, primarily from raw materials manufactured in the United States.

Typically, an audio system consists of: an audio signal source (turntable, FM tuner, CD player, etc.), an amplifier (either integrated or consisting of a separate pre-amplifier and power amplifier), and finally a speaker system. All these devices must be interconnected by suitable signal cables. Even if the component interconnections are theoretically simple; experience shows that the interconnection cables may greatly influence the quality of the signal reproduced by the audio system. The interconnection cables are known to influence at a minimum: the tone-color of the signal, the spatial reconstruction of the audio “image”, the amount of lost information, the focusing of the sound sources, the dynamic range, the audibility of the sound event, the naturalness of the reproduced sound, and the noise level introduced into the audio signal. These, as well as other variations and distortions imposed on an audio signal by an interconnect cable are all degradations of the reproduced signal with respect to the original event.


Air is our primary dielectric. The air tubes we utilize are comprised of polyethylene tubing; which complies with 21CFR177.1520 – Olefin polymer, hospital grade polyethylene. In our cable design the capacitance of the cable is controlled by the tube size, and electrical break down voltage is determined by the polyethylene tube. This combination minimizes capacitance and inductance, key contributors to distortion. The air tubes are arranged in topological configurations specifically designed to reduce mechanical resonance, and have high electromagnetic interference (EMI) rejection properties. The craftsman seals the ends of the tubes using our proprietary method which creates a “Uni-Tube”, reducing the interaction between conductors and the environment. This simply means the signal traveling through our conductors are shielded from external, internal environmental influences and self-imposed phase distortion found in most cabling. The result is a balance from low to high frequencies and no artificially induced distortion to the audio signal.

This approach to cable and shielding design, along with our use of premium materials dramatically improves the cable’s performance and your listening enjoyment.
