Highlights:

• Complementary Conductor Technology™: Uses two conductors of different diameters for better sound quality.
• Teflon dielectric: Reduces loss of audio signal energy.
• Cryogenic treatment: Improves cable structure and sound quality.
• Analoc2™ connector design: High purity and minimization of current disturbances.
• Silver-coated conductors: Ensures less resistance and better sound reproduction.
• 100% electromagnetic shielding: Protects against signal interference.
• Rhodium-plated RCA connectors: Improves connection and sound quality.

Signature Audio 40:

This advanced audio cable is designed with the latest technology to ensure an exceptional audio experience. With QED Signature's unique Complementary Conductor Technology, which uses two conductors with different diameters, a more nuanced sound reproduction is achieved, where high-frequency sound components are conducted more efficiently. Teflon dielectric is used to minimize the loss of audio signal energy, resulting in clearer and more defined sound.

Cryogenic treatment :

Cryogenic treatment of the cable improves the microstructure of the material, which in turn increases the quality and lifespan of the product. QED's extensive listening tests have shown that the cable with cryogenic treatment is preferred over untreated cables.

Analoc2 connector design :

Renewed with low mass, high purity copper connections, and now uses a high stiffness thermoplastic material in both the internal support structure and cable trunk relief to eliminate the harmful effects of eddy currents. The hollow, rhodium-plated, high-purity copper signal pins retain their design, while the efficiency of the slip ring, which locks the similarly plated, pure copper earth terminal in place, has also been improved.
This cable is not just an improvement in sound quality, it also represents an innovation in audio cable design
