Ultimate USB
Purist Audio Design proudly introduces the new Ultimate USB audio cable. This USB audio cable is designed specifically for computer audio applications and is a comprehensive upgrade of its predecessor, adding passive filtering and an all‑new cable design. The Ultimate uses the largest gauge conductors permitted by the USB standard, ensuring signal transmission up to 5 meters — far beyond the few meters typical of other computer USB audio cables. That means even if your computer is located away from your audio equipment, audio performance remains uncompromised.
Purist Audio Design’s Ultimate USB cable employs precision manufacturing and superior noise‑suppression techniques to deliver a richer, more natural sound compared with standard computer USB cables. The cable also uses low‑noise dielectric materials and dual shielding to further improve noise performance, better reveal musical detail, and widen dynamic range.
Note: some computer USB outputs cannot reliably drive longer ordinary USB audio cables. The Purist Audio Design USB audio cable is a high‑resolution, high‑speed cable capable of transmitting high‑quality DAC signals over distances far beyond what is normally expected on a variety of computer interfaces.
