Audioquest Coffee USB A-B

In 1982 Sony gave us the 'perfect sound every time', together with the attitude that 'all CD players sound the same, because digital is digital'. This has been refuted and differences in quality between CD players have been accepted as a fact. Next came separate transport and DAC station wagons under the premise 'all digital S / PDIF audio cables sound the same', until this too was refuted. Now the border has shifted again. Is digital audio really all ones and zeros? We don't believe it, and once you've had the chance to hear the Coffee USB, you won't believe it either.

MASSIVE 10% SILVER LADDER

Solid conductors eliminate distortion caused by the interaction of the strands and reduce jitter. Solid, silver-plated conductors are ideal for high-frequency applications such as USB audio. During transmission, these high-frequency signals remain almost exclusively on the surface of the conductor. Since this is made of high-purity silver, the reproduction comes very close to that of a solid silver cable, while the price is closer to that of a copper cable. This is a surprisingly inexpensive way to make very high quality HDMI cables.

MASSIVE, HIGH DENSITY POLYETHYLENE INSULATION

Any massive material adjacent to a conductor becomes part of an incomplete electrical network. Wire insulation and circuit board material absorb energy (losses). Some of this energy is stored and then released as distortion. The massive, high-density polyethylene insulation ensures the critical geometry of the signal pairs and minimizes the phase distortions otherwise caused by the insulation.

DIELECTRIC-BIAS-SYSTEM (DBS, US Pat #s 7,126,055 & 7,872,195 B1)

Any insulation slows down the signal on the conductor inside. If there is no voltage across the isolation, it slows down individual parts of the signal to varying degrees - a major problem with very time-sensitive broadband audio. AudioQuest DBS creates a strong, stable electrostatic field that saturates and polarizes (organizes) the isolation molecules. This reduces both the energy stored in the insulation and the various non-linear time delays to a minimum. The sound is created against a surprisingly black background with an unexpected richness of detail and expanded dynamics. The DBS batteries last for several years. A button with an LED display enables the battery charge status to be tested occasionally.

PACKING

Precision gold-plated connectors were attached with the best solder available. Through the selection of the flux and the know-how in metal science, the AQ solder could be optimized for the production of low-distortion connections. The audible difference between different plumb bobs is the result of the connection quality. AQ solder does not have a high silver content, because the more silver there is in the solder, the more difficult it will be to make a good connection.

UNIVERSAL SERIAL BUS DEVICE CLASS DEFINITION FOR AUDIO DEVICES

USB (Universal Serial Bus) was created by a group of companies like Intel, Hewlett-Packard and Microsoft (to name a few) to provide a truly universal standard to the world of personal computers, including devices such as hard drives, printers , Cameras and - more important for us - audio components. Protocols for the unadulterated transmission of audio via USB are integrated in the original descriptions. Great care and attention to detail have been invested here. As a result, a computer connected to a USB-enabled digital-to-analog converter can outperform the best compact disc players currently available. AudioQuest is dedicated to providing products that honor USB's ability to enable state-of-the-art playback.
