B.M.C. PureUSB 1

While conventional audio USB cables rely on elaborate material tuning to minimise transmission losses and interference, B.M.C.’s PureUSB1 provides a better solution

High-quality USB connections perfect the sound of modern D/A converters.
While conventional audio USB cables rely on elaborate material tuning to minimize transmission losses and interference, B.M.C.’s PureUSB1 offers a superior solution: Active electronics optimize the USB signal and eliminate distortions and transmission artifacts just before entering the D/A converter. Additionally, the USB power supply is filtered, resulting in a cleaner and more stable signal for noticeably improved sound quality.

Another advantage is the reduced dependency on cable length: While conventional USB cables degrade in sound quality with increasing length—sometimes leading to instability at high sampling rates—PureUSB1 maintains consistent performance, with little to no discernible difference between 2m and 5m.
B.M.C.’s PureUSB1 is available in 2m and 5m lengths.
