Audioquest Diamond coaxial cable

AudioQuest is an American brand specializing in digital and analog connections. The AudioQuest Diamond coaxial digital cable is a high-end digital connection.

AudioQuest Diamond: Features

The connectors are made of pure red copper and receive silver plating. The conductors are cold welded to the connector using a current of 8000 amperes.

The 0.41 mm² solid conductor is made of pure PSS silver. This is the highest quality offered by AudioQuest. Perfect-Surface Silver (PSS) minimizes distortion and maximizes linear RF noise dissipation.

Cable insulation is ensured by high-density polyethylene air-cell foam that prevents any interference harmful to sound quality. This cable also features a noise dissipation system inside its jacket based on six layers of carbon. It helps prevent radio-frequency interference (RFI). The alternating layers of metal and carbon-loaded synthetics “protect the shielding”.

The Coffee is the first digital cable from the manufacturer to receive a DBS polarization module. This module dissipates a voltage of 72V.

AudioQuest Diamond: Test and Listening

When listening, the importance of digital connections becomes immediately apparent, as the AudioQuest Carbon coaxial cable respects the original signal and reproduces the music with remarkable neutrality.

Moving from the AudioQuest Carbon to the Diamond represents a clear financial step up, but it must be acknowledged that the Diamond offers exceptional reproduction. It combines all the qualities expected from a digital connection. It delivers fluid reproduction with incredible spatialization. Its neutrality is associated with remarkable smoothness and dynamics. It is never aggressive or harsh, but it is extremely detailed and subtle without being analytical.
