  • Frequency-range extension
  • Rich, neutral mid-range and tight bass
  • Neutral sound and clear presentation
  • Wide sound-stage and spatial cues
  • Extremely low noise

LightSpeed Pure Energy technology

All LightSpeed power cord include a special Pure Energy electronics that can effectively filter DC components that contaminate the alternating current. This results in cleaner sinusoidal alternating current, which results in more efficient operation. The special of LightSpeed Pure Energy electronics is the lighting rings of the connectors that provide a unique look to Ultimate power cords.


Ultimate model has pure copper conductors and a special designed structure. Ultimate power cord has a characteristic triple braid structure, with pure copper conductors, special antistatic foil, tin-plated, dense woven copper shielding, synthetic polymer insulation and halogen-free polyester outer casing. The triple braid structure ensures a transverse positioning, thereby minimizing the inductive and capacitive effects of the parallel construction of the conductors, which negatively affect the alternating current phase accuracy. The layers between the inner conductors and the outer casing effectively reduces the effects of electromagnetic and radio frequency radiation from the environment and provide adequate protection for the electric conductors against environmental vibrations.

The LightSpeed Ultimate has Balanced triple quad-core structure conductors and 9 sq mm total conductive cross-section, providing balanced and continuous power to the connected devices. The advantage of the Balanced triple quad-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. The asymmetric cables, such as those with double-phase conductors, can cause continuous fluctuations in alternating current due to different cross sections and electrical parameters. 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 inner helix design that effectively reduces the cable’s own capacity and inductance. The Balanced triple quad-core structure effectively reduce the skin effect, as conductors are not only composed of elementary strands, but are arranged in separate groups. The cross-sectional of the multi-core conductors 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 Ultimate model received high-quality, hand selected polymer-composite connectors with pure 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 Ultimate modell a unique look. The Ulitimate power cords is only available with classic Pure White lighting.

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

LightSpeed Ultimate power cords is available with US or EU plugs and special EU/UK adapter.
Available lengths: 120 cm, 180 cm and custom sizes.

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