EFF-IX Stereo Phono Audio Cable:

The SUPRA EFF-I Analog Audio Cable is a high-end solution for flawless signal transmission, even for the most subtle musical details. Designed with Equalized Frequency Flow (EFF) technology, it reduces the skin effect, where high-frequency signals are forced to the surface of the conductor. This ensures uniform impedance across all frequencies, eliminating issues like treble roll-off or phase shifts.

The purity of the conductors and precise silver plating deliver exceptional performance, especially at ultra-high frequencies, while the PE insulation ensures low capacitance and undisturbed signal transmission. The cables are shielded with aluminized PET foil, effectively blocking noise, and the Supra PPX connectors guarantee a robust and reliable connection thanks to their 24K gold-plated OFC pins and an expansion locking mechanism.

With a diameter of 7.8 mm and a beautiful ice-blue finish, the EFF-I cable combines aesthetics with functionality. It is ideal for high-end audio systems where every nuance matters. Manufactured in Sweden with precision and care, this cable is the perfect choice for audiophiles seeking optimal performance and durability
