Effect Audio has introduced a remarkable addition to its Signature Series II lineup— the Ares S II x Cadmus II (AxC II)—a flagship cable specifically designed for in-ear monitors (IEMs). This innovative cable merges the distinct characteristics of the Ares S II and Cadmus II cables, creating a unified solution that combines the best features from both models. It brings together the powerful warmth and richness of the Ares S II with the clarity and transparency of the Cadmus II, making it particularly suitable for fast-paced music genres such as rock, EDM, hip-hop, and metal.
The AxC II boasts an advanced design that emphasizes superior audio signal conductivity. With an 8-core construction and 26AWG wire size, the cable employs high-purity UP-OCC copper conductors alongside silver-plated copper strands. The hybrid configuration is built upon a Litz structure, ensuring excellent efficiency and signal fidelity. The copper conductors enhance bass response and deliver lush mids, while the silver-plated elements refine the treble, injecting a sense of air and precision into the sound signature. This synergy between the materials results in an agile, dynamic presentation tailored for high-energy tracks.
