LightSpeed Signature

Signature is the top-class representative of LightSpeed power cords, which in its structure evokes the flagship of the model family.

LightSpeed Pure Energy technology

All LightSpeed power cords include a special Pure Energy electronics that can effectively filter DC components that contaminate the AC. Thanks to this, the device comes with a cleaner, sinusoidal alternating current that results in more efficient operation. The other part of LightSpeed Pure Energy electronics is the lighting rings of the connectors that provide a unique look to Signature power cords.


LightSpeed Signature has high-purity penta-core copper conductors with increased cross-section and reduced resistance. The appearance of the Signature model also has a characteristic triple braid structure, which ensures a transverse positioning, thus minimizing the inductive and capacitive effects of the parallel construction of the conductors, which influences the phase accuracy of the alternating current.

The LightSpeed Signature model’s inner high purity copper conductors are covered with special anti-static film, tin-plated, dense woven copper shielding, synthetic polymer insulation, a polyester damping layer and a self-developed Black Helix shield outer casing. The improved polyester layer has a dielectric constant lower than the often used Teflon insulation and provides adequate protection against vibrations from the environment.

The Black Helix outer layer does not only provides a unique appearance to the Signature, but the special polymer film with a 500-nanometer thick metal layer does not allow external radiofrequencyal and electromagnetic radiation to penetrate the cable. The electric fields generated by the current in the copper conductors are effectively attenuated by the internal shielding, while the Black Helix layer is responsible for external electromagnetic and radiofrequecies noise protection, which together reduces the negative interaction between the current flowing in the conductor and the insulation.

The LightSpeed Signature has a symmetrical Balanced penta-core conductors design, providing balanced and continuous power to the connected devices.The advantage of the Balanced penta-core design is the symmetry, as all wires have the same cross-section and electrical parameters, providing balanced, continuous and stable performance as opposed to asymmetric cables. In the case of asymmetric, for example cables with an double phase conductor, cross-sectional and electrical parameters other than the other conductors can cause continuous fluctuation due to alternating current. Even the slightest fluctuations in the power supply can affect the stable operation of audio and video devices, as it can cause continuous noises in the sound and picture.

In addition to the symmetrical design, the conductors also have a Helix design that effectively reduces the cable’s own capacity and inductance. The penta-core structure effectively reduces the skin effect, as conductors are not only composed of elementary strands, but are arranged in separate groups. The cross-sectional surface of the multi-stranded conductors remains small enough to prevent the skin effect from developing, but overall, the conductors have an adequate cross-section to provide optimal power supply.


The LightSpeed Signature model received high-quality, hand selected polymer-composite connectors with high-purity copper contacts inside. The Rhodium-silver coating on the outside of the contacts provides the right connection, which has measurably better electrical parameters than for example gold coating and is more resistant to environmental impacts.

In addition to the high quality of the connectors, the special look is also emphasized by the built-in LED lighting. The lighting rings of the connectors give Signature a unique look. The Signature power cord is also available with special Dark Red lighting in addition to the classic Pure White.

The Signature power cords are built with high precision hand assembly and after the last quality check, they come in a special anti-static fabric bag and laser engraved natural wooden box.

The LightSpeed Signature power cords is only available in one size, as the cable length is based on the most optimal parameters.

NOTE: To get the best quality of LightSpeed power cables, it needs a “burn-in” period. After about 10-14 days of using LightSpeed cables, the sound quality becomes more life-like.
