About the QED QE7814
From our tech experts at CEN
The QED Performance QE7814 is the 1.5m length of QED's USB Type A to USB Type B cable for audio and data. It links a computer with a standard USB-A port to a device with a USB-B socket, such as a desktop DAC.
Who it suits
Pick 1.5m for a typical desk where the computer sits under or beside the desk and the DAC on top. For a DAC right next to a laptop, the 0.75m QE7811 is tidier, and the 3m QE7817 suits a computer further from the hi-fi.
Our tech experts advise
Confirm your DAC or device uses a square USB-B socket rather than USB-C. Connect directly to a port on the computer instead of through a hub, then choose the DAC as the sound output. Route the cable so it is not pulled when you move the computer or chair. Browse our QED collection.
