The QED Supremus Zr is the reference speaker cable of the Signature range. It gathers more than five decades of analogue-transmission development. Its design aims to preserve the integrity of the music signal end to end.

The Supremus Zr adopts zirconia plugs and barrels, a ceramic highly resistant to wear and eddy currents. A cold-weld system unites the conductors and plug parts. The rhodium-plated locking design ensures optimal contact with the posts.

Its 6.2 mm² very-low-resistance conductors let the amplifier fully control the speakers. Aircore technology spreads the current evenly across the audio band. A cryogenic treatment refines the copper microstructure.

The Supremus Zr comes in 2, 2.5, 3, 4 and 5 metre pairs. It equips the most ambitious hi-fi systems. Choose the length that matches your layout.
