Evolution of new-age USB Cables

Speed is critical for USB audio because time relationships within the digital stream are important for the reconstruction of analog waves which brings information and music to our ears. If you think digital audio is really just ones and zeros, experience Diamond USB for a change of mind.

Solid 100% perfect-surface silver conductors:

It provides extreme clarity and dynamic contrast when perfect surface technology is applied to extreme-purity silver. A major source of cable distortion, solid conductors prevent strand interaction. Eliminating harshness and pouring in more clarity, high-purity perfect surface silver minimized the distortion in the grain boundaries that exist within the metal conductors.

Foamed-polyethylene insulation:

While circuit board materials absorb all the energy, some energy is stored and released as distortion. Diamond USB uses air-filled Foamed-Polyethylene Insulation because of Polyethylene's low-loss and distortion profile and, also because air absorbs next to no energy. Unlike other materials, the Foamed-PE contains air and causes much less out-of-focus effect.

3-layer carbon-based noise-dissipation system:

The synthetics loaded with metal and carbon prevents most RFI from reaching the equipment's ground plane.

Dielectric-bias system:

AudioQuest's DBS creates a strong electrostatic field saturating and polarizing the molecules of insulation resulting in minimum energy storage in insulation and multiple non-linear time delays.


The silver plated pins are warily attached with the best solder. Optimized to make a low-distortion connection via flux and metallurgy, AQ solder's minimal silver content assures a strong and stable connection. The quality difference we hear is because of the quality of connection established.
