Supra USB digital audio cable

The standard USB cable is fitted with a Type A USB connector at one end and a choice of connectors at the other (such as Type B, Mini-B and Micro-B and as from Spring 2024, the Type C version is now available).

As such, it is designed to act as a digital audio cable, between a computer/streamer and a D-to-A convertor (a "DAC"), carrying audio signals from the former.

In this way, you can play your music stored on your computer or mobile phone/tablet or media player, via your hi-fi system (if the aforementioned DAC is connected to an audio input of your stereo system).

In the November 2012 issue of What Hi-Fi, the Supra USB cable won a convincing 5 stars review - it was compared against Audioquest Cinnamon USB (59 and 4*), Clearer Audio Silver-line USB (40 and 3*) and Russ Andrews Kimber USB (52 and 4*).
