The QED Reference Hi Res USB A-B Graphite is a premium USB Type A to Type B cable created for music lovers and demanding listeners who use a computer, laptop, streamer or music server as a digital source. It is designed for connections to a USB DAC, integrated amplifier or other hi-fi component with a USB-B input. As an upgraded New Reference High-Resolution USB cable, it sits in QED’s range as a carefully engineered option for systems where stable data transfer, format compatibility and clean digital connectivity matter.
QED has focused this cable on the practical demands of high-resolution audio playback. The Reference Hi Res USB A-B Graphite supports 32-bit, DSD and MQA signals when the connected source and DAC are also compatible. Clear Path Audio technology is designed to isolate the power and data lines inside the cable, helping to maintain a cleaner transmission path. The Impedance Controlled Data Lane aims to minimise jitter and timing errors, while the 90Ω +/- 5% characteristic impedance, low signal-pair attenuation and 480 Mb/s maximum data rate support reliable USB audio operation.
This QED USB A-B cable is a strong match for desktop listening, dedicated hi-fi racks and modern digital audio systems where a USB DAC forms the heart of the setup. The 7 mm outer diameter gives the cable a robust feel, and the available lengths of 0.6 m, 1 m, 2 m and 3 m make it easier to choose a neat installation without excessive slack. Pair it with a capable DAC or streamer, keep the connectors clean, and avoid tight bends for consistent performance. Choose the QED Reference Hi Res USB A-B Graphite to refine the digital link in your system.
