Principal performance

Jorma Prime established Jorma Design as one of the most respected high-end cable companies. Launching as a “no expense spared” series, it met with worldwide critical acclaim.

The cables are crafted with the finest materials including Gold and ultra-fine Copper (0.5mm2), and use conductors that took over six months to develop.

Bybee Slipstream Quantum Purifiers eliminate sub-audible noise, unmeasurable by typical test-bench instruments, producing previously unattainable resolution.

Jorma Prime offers natural, transparent sound; it’s one of the finest cable series that the market has to offer.
