Reference USB

Reference digital X2 interconnect designed for connecting PC and Mac based streaming devices to USB DAC's based on shielded dual non-coaxial twisted OCC conductors construction. ImpedanceControl technology helps keep dynamics and coherence. Very high conductivity, low internal reflections and low capacity are perfect for transmitting digital signals. Very good shielding helps to keep signal free of artifacts. Balanced filtering and triple shielding for most advanced audiophiles.

Four highest purity 7N OCC (Ohno Continuous Cast)solid 19AWG (0.64mm2) active conductors  in dual T3 configuration with ImpedanceControl.


Hi-End grade low density demagnetizing polyethylene (DM-PE) insulation. Seven layers / single group T3 construction with Impedance control. High gloss metallic PVC outer layer.


Triple shielding consisting of thick conductive PVC layer and copper foil effective in high frequencies and thick OFC braid with almost 99% coverage.


Hand soldered ultra low resistance USB. White metallic color. Diameter:2x8mm










Triple shielded non-coaxial construction X2 general purpose hi-end grade digital interconnect cable for experienced hi-end enthusiasts. Ideal for for use with more expensive systems. Brings improved details and dynamics when compared with SuperBlack USB.  Hi-End grade very low density demagnetizing insulation prevents phase shift and signal change and soft internal PVC layer reduces vibration and mechanical noise. Impedance control technology tights conductors so well that they cannot move from each-other even when cable is extremely bended. Result is very stable signal in all situations. X2 construction effectively doubles conductor size and vibration dumping so the signal is much clearer and precise. High frequency shield based on conductive PVC layer and copper foil is 100% effective in shielding very high frequencies and higher layer thick and dense OFC braid prevents any other possible external interference. Special hand soldered USB connectors with ultra low resistance help to  minimize internal reflections and signal more consistent. Adding additional USB A connector in 2A-B version gets that separation even further so both wire pairs never cross each other.

Solid conductors

Construction made of solid conductors eliminate internal reflections and higher conductivity and precision.


Conductors made solely of ultra high 7N purity Japanese Oxygen-Free Copper made by special patented process called Ohno Continuous Cast (OCC) are state-of-the-art of contemporary high-end cables.

Ultra Low Resistance connectors

Fitted with special ultra low resistance connectors, cables are clearer and more precise.

Impedance Control

Geometry of conductors that are tight together in twisted pairs or threes by dedicated layer that keeps distance between wires absolute so impedance will not change even when cable is bended.

listening tips

"Rock or Bust"

From first tunes, there is vital guitar with lots of dynamics and bass drum is very alive. With good hardware nothing gets confused.

Rock or Bust, COLUMBIA, 2014

Depeche Mode
"Black Celebration"

Very slow and gentle beginning turns into rage of ultimate electronic sounds of the 80's that tends to be annoying when anything is wrong with the setup. But if You got it right, it is real pleasure to listen.

Black Celebration, MUTE, 1986

Rage Against The Machine
"Killing in the Name"

Epic bass guitar combined with drums in perfect harmony creates strong impression and You need pretty fast system to enjoy all the details.

RATM, Epic, 1992

Norah Jones
"Good Morning"

Gentle guitar and her beautiful voice is perfect for slow waking up with morning coffee on a table. And then comes the violin, a lot of details to listen to in a tweeter.

...Little Broken Hearts, BLUE NOTE, 2011
