Description

Effect Audio introduced the Signature Series II, a major update two years after the first series set industry benchmarks. The Effect Audio Cadmus II, a high-performance IEM upgrade cable, is designed to deliver precise and reliable audio quality. Its Copper central solid-core structure ensures stable signal transmission with minimal interference, resulting in clear and accurate sound reproduction. The 26AWG 8-core braided construction enhances low-frequency performance, offering impactful sub-bass, rich tonal balance, and a wide, immersive soundstage. Durability is ensured with EA Ultra Flexi™ insulation, while EPO Pro ergonomic optimization provides flexibility and comfortable handling for daily use. The modular ConX connector system makes it compatible with a wide variety of IEMs, offering adaptability across multiple devices. Each Cadmus II cable is handcrafted with precision, combining advanced engineering with a forward-thinking design to meet the demands of modern audiophiles.

SOURCE OF INSPIRATION

Every journey begins with a spark of hope, carrying us through endless miles and infinite possibilities. Rooted in the wisdom of the Classics, where greatness first took flight, we push forward to create a legacy that reaches even greater heights. Like Ares, Cadmus, and Eros—heroes whose stories evolved through time—we honour tradition while embracing change. With innovation as our guide, we craft solutions that combine better ergonomics, advanced materials, and visionary designs. Our path is clear. Our mission is bold. The next chapter begins here.

PREMIUM UP-OCC SILVER-PLATED COPPER LITZ CABLE

The UP-OCC Pure Copper construction in the 8-wire configuration by Effect Audio in Cadmus II is engineered to deliver exceptional sound clarity, warmth, and fidelity. This high-purity copper enhances audio detail, providing a richer, more immersive listening experience. The meticulously designed 26AWG 8-wire braid ensures consistent, interference-free performance, optimizing signal integrity for a seamless and uninterrupted audio output. Crafted with precision and cutting-edge technology, Effect Audio sets the standard for high-performance, audiophile-grade cables, ensuring an unparalleled listening experience.

SOLID CORE CONSTRUCTION FOR DURABLE AND FLEXIBLE DESIGN

The Effect Audio Cadmus II Upgrade Cable For IEM is built with a 26AWG 8-wire configuration that offers significant ergonomic improvements, enhancing both flexibility and portability for a more comfortable and customizable listening experience. It introduces Copper Central Solid Core technology from the CODE Series, using a single, continuous conductor to eliminate gaps and reduce resistance. This results in improved conductivity and cleaner, more accurate audio transmission, especially at higher frequencies, ensuring a superior listening experience.

MODULAR DESIGN WITH CONX CONNECTORS

The Cadmus II features ConX connectors on the IEM side. This modular design allows you to easily switch between different connector types (MMCX, Pentaconn Ear, IPX, A2DC) by purchasing optional ConX adapters, expanding the cable's compatibility with a wide range of IEMs. The source side terminates in a standard Rhodium-plated brass 4.4mm straight plug. Effect Audio is a leading manufacturer of handmade high-end upgrade cables based in Singapore, renowned for its meticulous craftsmanship and dedication to delivering a superior listening experience. Each cable is meticulously crafted using the finest materials and innovative technologies to ensure exceptional audio performance and durability.
