PAUL'S REFERENCE Diamond USB

PS Audio's choice for our Reference System

Connecting computers to DACs is one of the more tricky applications in high-end audio. Here, it all matters. Great care must be taken to ensure the perfect interface between the noisy computer environment and that of a Digital to Analog Converter. The AQ Diamond is Paul’s favorite for this difficult application and comes highly recommended.

In the AQ Diamond, Perfect-Surface Technology is applied to extreme-purity silver to provide unprecedented clarity and dynamic contrast. Solid conductors prevent strand interaction, a major source of cable distortion, while Hard-Cell Foam (HCF) Insulation ensures critical signal-pair geometry. Noise reduction is critical to a cable’s performance. In the Diamond, an included RF Trap ensures that radio frequency noise will not be induced into the signal conductors from the DBS field elements.

PAUL’S REFERENCE Diamond USB

Product Description

Paul’s Reference USB Interconnect is what’s running our system in Music Room II. Sweet, open, detailed, yet without any evidence of grain, this curated AQ cable is Paul’s choice for PS Audio’s Reference System.

The AudioQuest Diamond USB cable is Paul’s pick to run between our server and DirectStream DAC.

Perfect Surface Technology is applied to extreme-purity silver conductors to ensure unprecedented clarity and dynamic contrast. Also featured is AQ’s Noise-Dissipation System (NDS), incorporating alternating layers of metal and carbon-loaded synthetics to “shield the shield,” absorbing and reflecting most of the noise/RF energy that would otherwise damage the audio signal before it reaches the layer attached to ground. Getting the noise and jitter levels as low as possible is a critical task for the USB cable in any computer/DAC system. To date, we’ve not found a better combination than Diamond and DirectStream. Openness, musical purity, and an analog-like tonal balance lets music breathe.

This product qualifies for our risk free in-home trial in the continental United States when purchased directly from PS Audio. Break-in on AQ Cables may be required for optimal performance.

Solid 100% Perfect Surface Silver

Perfect-Surface Technology applied to extreme-purity silver provides unprecedented clarity and dynamic contrast. Solid conductors prevent strand interaction, a major source of cable distortion. Extremely high-purity Perfect-Surface Silver minimizes distortion caused by the grain boundaries that exist within any metal conductor, nearly eliminating harshness and greatly increasing clarity compared to OFHC, OCC, 8N and other coppers.

Carbon Based 3-Layer Noise-Dissipation System

While it’s easy to accomplish 100% shield coverage, it’s far more difficult to prevent captured Radio Frequency Interference (RFI) from modulating the equipment’s ground reference. That requires AQ’s Noise-Dissipation System (NDS). Traditional shield systems typically absorb and then drain noise/RF energy to component ground, modulating and distorting the critical “reference” ground plane, which in turn causes a distortion of the signal. NDS’s alternating layers of metal and carbon-loaded synthetics “shield the shield,” absorbing and reflecting most of this noise/RF energy before it reaches the layer attached to ground.
