Know before you buy
The Cassiel cable typically offers improved clarity and a more precise soundstage. By using high-purity silver-plated copper, it helps sharpen micro-dynamics, making vocals and individual instruments sound more distinct and vibrant.
The Kevlar core provides significant structural reinforcement, which makes the cable highly resistant to stretching and daily wear. Despite this durability, the cable remains flexible and easy to manage during use.
Cryogenic treatment is a specialized process that alters the molecular structure of the metal conductors. This helps reduce internal resistance and improves signal transmission, ensuring the cable maintains its performance characteristics over a longer lifespan.
The Cassiel is available in both MMCX and 0.78mm 2-pin configurations. You should select the specific connector type that matches your IEMs at the time of purchase, as they are not interchangeable.
FlexiMax insulation is designed to be soft and pliable, preventing the cable from feeling stiff or prone to tangling. It allows the cable to drape naturally without creating microphonic noise when it brushes against your clothing.
