STELLAR AudioQuest Cinnamon Optical

PS Audio’s choice for our Stellar Series

When the question is “how can a fiber-optic cable change the sound?” The answer is easier to explain than for almost any other type of cable. If the light source were a coherent laser, firing into a vacuum, all the light would stay straight, arriving at its destination at the same time. Even if the LED light source in a Toslink system were coherent, the light entering a fiber-optic cable is scattered and dispersed by imperfections and impurities in the fiber. This can be measured as a loss of amplitude, but amplitude is not the problem: a 50% true loss would have no effect on sound quality.

The almost complete solution to this problem is to use hundreds of much smaller fibers in a 1.0mm bundle. Because each fiber is limited as to what angle of input can enter the fiber, there is far less variety, and far less dispersion over time. AudioQuest Cinnamon optical cables provide Stellar products with less dispersion in the fiber, and less dispersion by filtering the input angle. How simple is that! Listen and enjoy.

STELLAR AudioQuest Cinnamon Optical

Product Description

Optical may not transfer your highest resolution signals with complete efficiency, but it is a ubiquitous interface in the world of video and home entertainment, which cannot be ignored. AudioQuest Cinnamon optical, connecting your 2-channel Stellar system to a television or cable-box, brings new life to movies and television programs.

Imperfections in standard optical fiber scatter the light information, leading to sound with less clarity and a need for more error correction The superior fiber and finely polished optical interface of AudioQuest Cinnamon fiber-optic cable avoids these problems.

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.

Lower-Dispersion Higher Purity Fiber

The problem is that the dispersed light does get through the cable, but only after it has taken a longer path, like a pool ball bouncing off the side-rails, causing it to arrive later. This delayed part of the signal prevents the computer charged with decoding this information from being able to decode properly, or even at all. The inability to decode shows first at higher frequencies (not audio frequencies, this is a mono stream of digital audio information), so reduced bandwidth is a measurable signature of light being dispersed by a fiber. The punch line: The less dispersion in the fiber, the less distortion in the final analog audio signal presented to our ears. Using Lower-Dispersion Higher Purity Fiber, AudioQuest’s Cinnamon optical cables inhibit signal-dispersion and make a great match for Stellar digital products.

Finely Polished Optical Interface

A revolution in fiber optic cable design, Cinnamon optical uses several highly polished polymer fibers instead of a single plastic conductor. These polymer fibers are more efficient at conducting light (information) giving Cinnamon optical greater resolution and improved tonality over any standard optical cables, and most after-market ones too. Cinnamon preserves optical’s vanishingly low noise and offers dynamic range. The impact of Cinnamon optical is profound, with surprising transient performance and excellent dynamic gradations.
