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)
For 2024, the Type-C terminated version is now available - see
here .
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*).

It also received the What Hi-Fi "USB Cable of the Year"
award for 2012.
Shown above is: USB A-B cable (factory terminated).
Type A-mini B and A-micro B are also available.
Standard Features:
High Performance, High Speed - Uses a flexible cable with dual screens
for the best RF pick-up protection.
One twisted pair for data and one twisted pair for power, with individual
screens for minimal cross-channel interference.
Low capacitance and efficient noise rejection maintain signal integrity
in long run interconnects.
PE-insulated wires with correct 90 Ohms impedance design.
24K gold plated and shielded connectors.
The connectors are moulded to withstand tough applications and long
term use.
Maximum Data Transfer Rate: 480 Mbits/second (as per USB 2.0 specifications).
Please note:
While USB 2.0 and 3.0 are physically and electrically compatible,
USB 3.0 is a dual-link system that is not currently used for USB
Audio.
Connectors used to terminate USB cables are:
1) Standard Type A to Standard Type B - for use with most mains-powered
DACs - available in the following lengths:
0.7m, 1m, 2m, 3m, 4m, 5m, 6m, 8m, 10m, 12m, 15m
