We currently offer 2 grades of USB2 Audio Cables:
- AA USB
- AA Reference USB
The entry-level AA USB is an affordable high-performance USB2 Audio Cable with good musicality. It uses copper and silver alloy, not silver-plated copper, giving a good balance considering advantages and disadvantages of both pure copper and pure silver cables. It has a nice tonal balance with sufficient details and controls.
The AA Reference USB is meant for highly resolving systems giving more precise imaging and placement of instruments with tighter bass control. It has lower background noise and excels with complex music.
The suitability of copper versus silver-based USB Audio Cables is system dependent. In general, the copper and silver alloy version works for most systems.
All our USB cables have the VBUS and GND inside the same shield as the USB2 data lines. This makes the cable more manageable compared to having another stiff external wire for VBUS and GND. The picture below shows the conceptual diagram of how our AA USB cables are constructed. The parts used include premium parts originated from various countries, with the most expensive being the solid core cables for USB2 data lines.
Here are the details of the materials used for each grade of our USB cable.

The picture below shows a completed cable. Please note that the braided shield goes all the way to the USB A & B connector casing to ensure the data and power lines are protected from EMI. The braided shield only connects to the source (USB A) and is not connected to the DAC side (USB B).
