AA Reference USB Audio Cable


High-performance USB2 Audio Cable made of pure-silver solid conductors for data lines and copper-silver alloy conductors for VBUS and GND.



4N pure-silver solid conductors for D+/D-
OCC copper + 20% OCC silver alloy solid conductors for VBUS & GND
EMI shielded

Cable Construction

The above diagram gives the inner view of the cable.  Exotic audio components sourced from various countries are used.  As the USB2 data lines characteristic impedance depends on the twisting geometry of the data pair, i.e. the distance between the twisted conductors, bending the cable too much can alter its impedance value.  It is important to treat the cable gently when connecting from the source to the DAC.

During cable construction, we test the USB2 data pair to be within 90 ohms +/- 4%, tighter than USB2 specifications of 90 ohms ± 15%.



  • 2-year limited warranty. Cable should not be bent excessively but gently
  • Please hold the USB A or B connector when connecting and disconnecting, not the wire.
  • Upgrades may be offered in the future.
    Cable needs to be returned / exchanged with some fees.
