QED Genesis Silver Spiral
QED Genesis Silver Spiral speaker cable with concentric geometry, designed to connect an amplifier to speakers with minimal line losses.
Description
The QED Genesis Silver Spiral is a speaker cable designed to connect a hi-fi amplifier to a pair of speakers. It stands out for its particular internal construction, designed to transmit the audio signal with as little degradation as possible over the length of the cable.
Its structure is based on 9 insulated conductors arranged around a central LDPE core, in a concentric spiral geometry. This arrangement, combined with a cross-section of 2 x 5.5 mm², aims to limit parasitic phenomena that can affect the signal over long distances. The loop resistance of 6 mOhm/m remains low, which limits energy losses between the amplifier and the speakers. The capacitance of 76 pF/m and the inductance of 0.46 µH/m, as well as the dissipation factor of 0.0070, characterise the electrical behaviour of the cable and its ability to preserve the coherence of the transmitted signal.
This type of cable is aimed at hi-fi enthusiasts wishing to take care of the connection between their electronics and their speakers, particularly on systems where the quality of the connectors and cabling can have a noticeable influence on the sound rendering. It is suitable both for a classic stereo configuration and for more demanding systems where every link in the chain is chosen with care.

What to check before buying used
Check the integrity of the connectors at each end (banana, spade or bare wire): oxidation or a loose crimp can degrade contact and cause losses or parasitic noise. Inspect the sheath along its entire length for marked creases, cuts or crushing marks, which could alter the internal spiral geometry and therefore the electrical performance. A simple continuity test on the 9 conductors ensures that no strand is broken before installation.
