Coffman Labs may be unapologetically analog, but even a dedicated analog system can benefit from the flexibility of a high-resolution digital source. The JL-USB is designed to bring the warmth and spirit of analog to a digital source, providing a clean, stable link between your source and DAC while preserving signal integrity.
Built with three strands of our purpose-built 22G UltraWire©, the JL-USB is hand-braided and treated with our proprietary liquid-nitrogen cryogenic process, with careful attention given to every material and connection.
The result is a natural, balanced presentation with excellent extension, clarity, and tonal coherence—without the etched or overly bright character sometimes associated with high-frequency digital reproduction.
Handmade in Oregon, the JL-USB brings our approach to materials, craftsmanship, and thoughtful engineering to one of the less glamorous—but necessary—connections in a modern audio system.
A meaningful step beyond ordinary listening, bringing greater clarity, balance, and connection to the music.
Improved dynamics, presence, and tonal richness draw you further into the performance and keep your attention locked in.
A wider, deeper, more dimensional presentation creates the feeling of being surrounded by the music rather than simply hearing it.
Music takes on an effortless, floating quality with heightened space, delicacy, and realism that feels almost untethered from the system itself.
The fullest realization of the performance—where detail, emotion, dynamics, and spatial realism come together in a deeply transformative listening experience.
Handmade by Coffman Labs in collaboration with the audio veterans at Jena Labs, sharing a commitment to precision and performance. Every cord is hand-braided for optimal alignment and phase consistency, while all components and wire undergo LN2 cryogenic treatment to reduce noise and enhance signal integrity.
