AudioQuest Diamond 72v DBS USB A - B 1,5m USB Cable

AudioQuest Diamond USB Type A to Type B Data Cable

In 1982 Sony gave us "Perfect sound forever," along with the attitude that, "it's just digital, so all CD players sound the same." That was disproved and qualitative differences between players became accepted truth. Next came separate transport and DAC combos, which brought with it the attitude that "all S/PDIF digital audio cables sound the same..." until that too became disproved. Now the frontier has moved once again. Is digital audio really just ones and zeros? We don't believe so, and once you've had a chance to listen to Diamond USB, you won't think so either...

Solid 100% Perfect-Surface Silver Conductors (PSS) :

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 which exist within any metal conductor, nearly eliminating harshness and greatly increasing clarity compared to OFHC, OCC, 8N and other coppers.

Solid High-Density Polyethylene Insulation :

Any solid material adjacent to a conductor is actually part of an imperfect circuit. Wire insulation and circuit board materials all absorb energy (loss). Some of this energy is stored and then later released as distortion. Solid High-Density Polyethylene Insulation ensures critical signal-pair geometry while minimizing insulation-induced phase distortion.

Dielectric-Bias System (DBS, US Pat #s 7,126,055 & 7,872,195 B1) :

All insulation slows down the signal on the conductor inside. When insulation is unbiased, it slows down parts of the signal differently, a big problem for very time-sensitive multi-octave audio. AudioQuest’s DBS creates a strong, stable electrostatic field which saturates and polarizes (organizes) the molecules of the insulation. This minimizes both energy storage in the insulation and the multiple nonlinear time-delays that occur. Sound appears from a surprisingly black background with unexpected detail and dynamic contrast. The DBS battery packs will last for years. A test button and LED allow for the occasional battery check.

Silver-Plated Terminations :

Precision direct-silver plated pins are carefully attached with the very best solder. Through choice of flux and metallurgy, AQ solder has been optimized to make a low-distortion connection. The difference you hear between solders is a result of connection quality. AQ Solder does not have a high silver content because the more silver there is in solder, the more difficult it is to make a good connection.

Universal Serial Bus Device Class Definition for Audio Devices :

USB (Universal Serial BUS) was established by a stalwart group of companies such as Intel, Hewlett-Packard, and Microsoft (just to name a few) in order to give the personal computing world a truly universal standard and means to connect devices such as hard drives, printers, cameras, and, more importantly to us, audio components. Included in the original description are protocols for the pristine transfer of audio over USB. Great care and sensitivity went into this. Consequently, a computer connected to a USB-enabled digital-to-analog converter can outperform the best compact disc players available today. AudioQuest is committed to contributing products that honor USB's ability to deliver state-of-the-art performance on this new and wonderful frontier.

About AudioQuest

AudioQuest has been the largest cable supplier to the high-end specialist market for many years. AudioQuest is sold in several hundred outlets in the US and in over sixty countries. Bill Lowe (Founder) is especially pleased that this success has been possible despite his insistence that the foundation of the company, and the foundation of AudioQuest marketing, must be the performance of the product. In the audio world, many professionals have learned that it is not always convenient to listen to the products they sell … they might learn something they don’t want to know! Bill has always understood the challenge of basing the existence of AudioQuest on the performance of the product. However, to Bill, this is the only reasonable way to do business and the only acceptable way to combine his passion for music (and all things high performance), with his need to make a living.
