AudioQuest USB Cinnamon

Cinnamon

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 Cinnamon USB, you won’t think so either…

SOLID 1.25% SILVER CONDUCTORS: Solid conductors eliminate strand-interaction distortion and reduce jitter. Solid silver-plated conductors are excellent for very high-frequency applications, like USB audio. These signals, being such a high frequency, travel almost exclusively on the surface of the conductor. As the surface is made of high-purity silver, the performance is very close to that of a solid silver cable, but priced much closer to solid copper cable. This is an incredibly cost effective way of manufacturing very high-quality USB cables.

FOAMED-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 released as distortion. Cinnamon USB uses air-filled Foamed-Polyethylene Insulation because air absorbs next to no energy and Polyethylene is low-loss and has a benign distortion profile. Thanks to all the air in Foamed-PE, it causes much less of the out-of-focus effect common to other materials.

TERMINATIONS: Precision gold-plated plugs 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.

USB Audio (Universal Serial Bus):

For many applications, the speed of digital communication is important. Most visibly, “speed” is about transferring large files as quickly as possible, or carrying enough data for an HD video. For USB audio (and for

HDMI audio), “speed” is critical not because of how-much how-fast, but because time relationships within a

digital stream are critical to the reconstruction of the analog wave formthat brings information, music and joy

to our ears. Time-based damage (jitter) to this information within the data package makes the sound small

and flat instead of 3D, harsh and foggy instead of smooth and clear.

Features:

• Solid 1.25% Silver-Plated conductors eliminate inter-strand distortion.

• Digital audio conductors controlled for direction.

• Solid Polyethylene costs more than foam, but better ensures critical signal-pair geometry

While USB 2.0 and 3.0 are compatible, USB 3.0 is a dual-link system not used for USB Audio.
