This range uses labour-intensive techniques. We combine high-purity copper and silver with small, specific quantities of gold, chosen for their excellent sound reproduction characteristics. The copper, silver and gold used are monocrystalline, ensuring the removal of virtually all impurities. The entirely handcrafted construction is carried out using different dielectrics and multiple layers of shielding, wich is essential for a completely faithful signal transmission.

Padouk wood, handcrafted by luthier Jorge López, was chosen for its excellent ability to absorb unwanted vibrations. 
All of these techniques are used to protect the signal against electromagnetic and radio frequency interferences.

These characteristics give the Ra cables a solid construction and a full, clean and smooth sound, for a non-fatigue

and pleasant listening experience.

Due to complexity of its artisanal production, only limited units are manufactured each year.
