Black USB

Digital interconnect designed for connecting PC's and Mac's to USB DAC's based on quadruple shielded twisted OFC conductors construction with ImpedanceControl technology. High details and coherence. Very good shielding helps to keep signal clean and black metallic outer layer on twisted cable looks good.

Four high-purity OFC solid 24AWG (0.2mm2) conductors  in T2 configuration with ImpedanceControl.


Hi-Fi grade LDPE insulation. Nine(!) layers / two groups T2 construction. High gloss metallic PVC outer layer.


Quad shielding consisting of two thick conductive PVC layers, foil shield effective in high frequencies and high density OFC braid with >95% coverage.


Hand soldered gold plated USB connectors. Black metallic color. Diameter:8mm










Qua shielded USB A - USB B hi-fi grade digital interconnect cable for beginner hi-fi enthusiasts and music lovers. Ideal for use in lower to mid-priced systems to connect your USB enabled streaming device like computer or laptop to any USB D/A converter - standalone or integrated into amplifier. Improves resolution, details and dynamics. Hi-Fi grade LDPE insulation does not shift phase of the signal 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 two layers of conductive PVC is 100% effective in shielding very high frequencies combined with single aluminum foil wrap and dense OFC braid prevents any other possible external interference. Gold plated USB connectors hand soldered to wires ensure low internal reflections.

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.

...Little Broken Hearts, BLUE NOTE, 2011
