CODE 24 MK II is our definitive love letter to SPC enthusiasts, it delivers speed and transparency with clarity, while copper’s foundation preserves body and weight. The result is a sound that is fast, open, and powerful—free from harshness yet uncompromising in detail.
The MK II evolution introduces three precise improvements: over 20% more conductive material for stronger signal delivery and dynamic headroom, a 10% reduction in overall diameter for improved ergonomics, and the Quad-FlexPro™ Solid Core system, which enhances frequency control and stability across the spectrum. Together, these refinements push performance further while retaining structural integrity.
CODE 24 MK II surpasses the balance of its predecessors, defining itself with clarity, precision, and expansive scale—an SPC cable at its most accomplished.




Sound Profile
This next-generation performance is driven by our optimized Quad-FlexPro™ Solid Core System and Multi-sized Core Bundles with a Proprietary Multi-size Strands Blend of Premium UP-OCC Silver-Plated Copper Litz. The result is a sound signature defined by speed, finesse, and surgical control. Transients are razor-sharp, revealing the most delicate microdetails with immediacy and intent. The stereo sound field expands in both width and depth, while ultra-high frequencies extend with super-tweeter–like clarity, shimmering detail, and zero harshness. CODE 24 MKII is especially well-suited for IEMs with thicker or meatier tonal signatures—unlocking their resolution with precision across the entire frequency range.
The CODE 24 MK II is our definitive love letter to SPC enthusiasts, pushing the material's inherent strengths — its speed, control, and crystalline detail to their absolute maximum, making it the most transient cable in the Horizon Series. Read Less

CODE 24 MK II uses over 20% more conductive material than their predecessors. This increase in mass strengthens signal delivery, resulting in improved acoustic resolution, faster transients and more accurate detail retrieval.
2. 10% Reduction in Diameter
Despite the material increase, the cable is now slimmer thanks to the sleeve optimization. It keeps the same AWG size while improving overall flexibility and reducing bulk.
3. Quad-FlexPro™ Solid Core System
Building on the Quad-FlexPro™ Solid Core System, an evolution of our earlier Trio-Flex™ design. The central conductor is divided into four individually calibrated strands across three distinct sizes, each tuned to refine the lows, mids, and highs. This structure enhances compliance and stability, resulting in a cable that achieves both frequency accuracy and balanced musicality, while uniting solid-core performance with everyday comfort.

Hardware Design
Its dual-layer construction is defined by clean lines, chamfered edges, and tight geometric balance. This is not a design built on ornamentation—but one that achieves elegance through structure, symmetry, and purpose.
