Black Sub

Analogue interconnect based on shielded twisted OFC conductors construction with ImpedanceControl technology. Very high conductivity, low filtering and higher coherence pleases also more experienced audiophiles that do not want to spend too much. Best performance/price from lineup. Very good shielding helps to keep signal clean and black metallic outer layer looks beautiful. Designed for use with active subwoofers or central channels in multichannel systems.

RCA-RCA (XLR-RCA on demand)


Three high-purity OFC solid 18AWG (0.8mm2) conductors  in T3 configuration with ImpedanceControl.


Hi-End grade low density polyethylene insulation. Five layer / single group T3 construction. High gloss metallic PVC outer layer.


Dual shielding consisting of thick conductive PVC layer effective in high frequencies and OFC braid with >97% coverage.


Hand soldered multi-contact HollowPin RCA connectors. Black metallic color. Diameter:7mm










Dual shielded pseudo-balanced general purpose hi-fi grade mono analogue interconnect cable for advanced hi-fi enthusiasts and music lovers. Ideal for use with mid-priced systems. Improves resolution, details and dynamics and brings much better coherence and signal stability when compared with lower models. Main difference comparing to Grey Sub is that sound is more stable and precise. Hi-End grade low density insulation prevents phase shift 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 and higher layer thick and dense OFC braid prevents any other possible external interference. Special process hand soldered custom low capacity multi-contact HollowPin RCA connectors help to minimize internal reflections. It's aluminium CNC machined body perfectly shields soldered connections.

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.

HollowTip connectors

Fitted with custom HollowTip RCA or XLR connectors, lowering internal reflections and filtering.

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
