Black USB+

Digital X2 interconnect specially designed for connecting PC's and Mac's to USB DAC's based on triple shielded twisted OFC conductors construction with ImpedanceControl technology. Very high details and coherence. Best performance/price for this connection type from lineup. Very good shielding helps to keep signal clean and black metallic outer layer on twisted cable looks cool.

USB A - USB B (USB 2A - USB B, USB A - miniUSB/microUSB/USB C on demand)


Two and two high-purity OFC solid 23AWG (0.3mm2) conductors  in T2 configuration with ImpedanceControl.


Hi-End grade XLPE insulation. Six layer / single group T2 construction combined in X2 pair for complete separation of data and power. High gloss metallic PVC outer layer.


Triple shielding consisting of thick conductive PVC layer and foil shield effective in high frequencies and very high density OFC braid with >99% coverage.


Hand soldered low capacity 50u gold plated USB connectors. Black metallic color. Diameter:2x4.5mm










Triple shielded USB A - USB B (also available 2A-B or custom mini and micro USB and USB C connectors) hi-fi grade digital interconnect cable for advanced hi-fi enthusiasts and music lovers. Ideal for use in mid-priced systems to connect your USB enabled streaming device like computer, laptop, tablet or even phone to any USB D/A converter - standalone or integrated into amplifier. Improves resolution, details and dynamics and brings much better coherence and signal stability. Hi-End grade XLPE insulation helps signal stability 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. This helps to stabilize impedance and prevents higher capacity traps to filter signal or make reflections. Result is very stable signal in all situations. High frequency shield based on conductive PVC layer is 100% effective in shielding very high frequencies combined with single aluminum foil wrap and very dense OFC braid prevents any other possible external interference. Low capacity heavily gold plated connectors hand soldered to wires ensure very low internal reflections. Having X2 configuration with completely separated path for data and power signals helps reduce any interference. Adding additional USB A connector in 2A-B version gets that separation even further so both wire pairs never cross each other. Special version for small USB DAC's with mini, micro or USB C connector is also available on demand.

Solid conductors

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


Conductors made solely of high 4N purity Japanese Oxygen-Free Copper (OFC) free of any magnetic residue.

Low Resistance connectors

Fitted with special 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.
