NorStone Signature ST250

Signature ST250 represents the pinnacle of acoustic precision, combining cutting-edge technologies for crystal-clear sound reproduction. Made from pure OCC-6N and OFC-4N copper, this cable features an innovative structure of 19 concentric conductors using STAR technology.

Its triple shielding system offers exceptional acoustic insulation: a polyethylene sheath, a cotton fibre filling to attenuate micro-vibrations, and an aluminium mylar foil that sculpts a realistic, airy soundstage. Every technical detail contributes to perfect separation of the instruments, revealing every musical nuance.

Coated in a soft-textured anthracite grey, the cable has a diameter of 10 mm and is metrically marked for custom cutting to 100 metres. With a resistance of 0.006704 Ω/m, an inductance of 0.9944 μH/m and a capacitance of 93.088 pF/m, it pushes back the limits of audio transmission.

A cable that transforms listening into a sonic experience of unrivalled precision and depth.
