Semperfi USB-C To USB Type A Interconnect

Reference-Grade USB Audio

The SemperFi Series was created to deliver cables that get out of the way of the music.
By using Ohno Continuous Cast (OCC) 5N pure silver conductors and subjecting them
to a deep-cryo process, resistance and grain boundaries are minimised for lightning-fast signal transfer.
The result is a USB link that feels effortless, transparent, and free of the harsh edge often associated with lesser designs.

Shielding & Construction

Each cable is wrapped in a dual-layer system: a full-coverage foil wrap plus a 99.9% visual coverage braided copper shield.
This design suppresses RF/EMI noise and ensures timing accuracy in the USB stream.
All-metal connector shells improve grounding, while high-silver Japanese solder guarantees strong, low-resistance joints.
