Fusion 1 (2025)

Fusion 1 (2025) is the pinnacle of Horizon’s multi-material design. Formed from a sophisticated blend of UP-OCC Gold-Plated Silver, UP-OCC Pure Silver, and multiple copper variations, it achieves a balance no single conductor can deliver a richer and more detailed sound presentation. The result is sound that is powerful, transparent, and harmoniously complete.

Its Tri-Strata Layering (TSL) geometry arranges 40 individually sized bundles across three layers, regulating current flow with precision. This structure expands the stage while maintaining coherence, projecting detail with accuracy and preserving natural timbre. Fusion 1 (2025) delivers both resolution and musicality—an experience that is layered, controlled, and deeply engaging.

The redesigned Y-split engineered from aluminum, drawing inspiration from propulsion systems and precision aerospace components. Defined by strength and technical efficiency, it reflects Horizon’s commitment to innovation—where advanced materials and precise engineering converge to shape the future of cable craft.

Sound Profile

FUSION 1 (2025) expands the boundaries of soundstage in every direction, delivering a more holographic and immersive listening experience with enhanced resolution, sharper imaging, and a vibrant sense of presence. Its spacious performance is made possible by a sophisticated internal architecture, featuring 40 multi-sized core bundles that allow for layered current flow and precise spatial control. 

Tri-Strata Layering Fusion Mix

At the heart of Fusion 1 is EFFECT AUDIO’s most intricate build to date, their proprietary Tri-Strata Layering™ (TSL) geometry. Three precisely engineered layers unite UP-OCC Gold-plated Silver, Pure Silver, and close to half a dozen premium Copper variants, including an improved ergonomic solid-core copper at the center.

Within these layers, 40 multi-sized core bundles are arranged to maximise conductivity, preserve signal integrity, and ensure tonal consistency across the frequency range. This unprecedented blend of materials and geometries delivers a clear, measurable step up in resolution, bass authority, and long-listening comfort over previous solid-core designs. 

Hardware Design

The Y-split of the FUSION 1 (2025) embodies a forward-looking vision of engineering. Machined from lightweight aluminum and finished in a soft metallic gold, its compact, modular form draws inspiration from propulsion systems and precision aerospace components.

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.

It’s a seamless blend of precision design and technical innovation, resulting in a bold yet understated visual evolution.
