Supra Ply 3.4 Screened
Screened speaker cable Supra Ply 3.4, made of tin-plated OFC 5N copper, designed for medium to high-power hi-fi installations.
Description
The Supra Ply 3.4 Screened is a connecting cable between amplifier and speakers, designed to transmit the audio signal with minimal alteration. Its function is to link the amplification chain to the loudspeakers while preserving the dynamics and definition of the sound as accurately as possible over the entire cable run.
Its rectangular cross-section contributes to a dynamic reproduction capable of conveying the finest transients, while limiting interference and distortion. The conductor is made up of multiple strands of grade 5N OFC (Oxygen Free Copper), meaning a purity greater than 99.999%, tin-plated to enhance their resistance to corrosion. The chemically stable PVC insulation helps maintain the cable's performance over time. Screening is also incorporated: on compatible systems, it improves the signal-to-noise ratio.
This cable is intended for hi-fi enthusiasts wishing to equip a medium or high-power installation, whether the distance between the amplifier and the speakers is short or long. Its design suits it to both compact configurations and installations requiring longer cable runs.
What to check before buying used
Check the condition of the connectors (spades or banana plugs): oxidation, loose crimping or weakened soldering are the first signs of wear on this type of cable. Examine the PVC sheath along its entire length for cracks, pronounced kinks or crushed areas that could compromise the screening and the contact of the copper strands. A channel-by-channel continuity test ensures that no strand is broken inside the rectangular cross-section.
