Absolute Integrity. Controlled Power.

The Pure Line Audio TriCore Ultra Speaker Cable is engineered for one of the most demanding signal paths in audio reproduction: the connection between amplifier and loudspeaker.

At this point in the signal chain, current is high and dynamic.
Any resistance, interaction between conductors, or uncontrolled geometry directly limits control, timing, and stability.

Once energy is restricted here, it cannot be recovered downstream.

This cable exists to do one thing:
preserve the full integrity of the amplifier output as it reaches the loudspeaker.

The result is not a change in sound, but a more complete one.

Triple Material Architecture, Purpose Built

No single conductor material is complete on its own.

TriCore Ultra combines three solid core conductors, each selected for a defined electrical role within the signal path.

30 % solid core pure silver, 5N purity with 1 percent gold, individually insulated in PTFE.
Used where refinement, stability, and micro detail matter most. High frequencies remain smooth, resolved, and controlled, with no glare or sharpness.

30 % solid core UP OCC copper, individually insulated in PTFE.
Forms the tonal foundation of the cable, delivering linearity, natural weight, and organic midrange timbre with stable image scale.

40 % solid core silver plated OFC copper, individually insulated in PTFE.
Reinforces speed, transient precision, and low frequency authority, improving control and bass definition under load.

Each material is applied where its electrical behavior is strongest.
Nothing is duplicated.
Nothing is decorative.

Geometry That Controls Interaction

Different conductor gauges are intentionally combined.

The braiding geometry is manually executed to reduce interaction between conductors, cancel external interference, and lower impedance without artificial filtering.

This geometry allows the strengths of each material to reinforce each other instead of competing.

All braiding and assembly is done by hand and individually inspected.

Electrical Performance and Insulation

Through controlled material selection and precise geometry, the TriCore Ultra Speaker Cable achieves an impedance of 2.6 ohm per kilometer, improving current delivery, system stability, and control under dynamic load, particularly with demanding loudspeakers.

Each solid core conductor is individually insulated in PTFE to prevent dielectric interaction.
The completed cable is finished with two layers of natural organic cotton, providing mechanical damping without introducing synthetic dielectric effects.

Listening Results

With the TriCore Ultra Speaker Cable in place, the presentation becomes more stable, controlled, and resolved.

High frequencies retain their detail while remaining smooth and composed, even during complex passages. Fine nuances and micro information emerge without edge or emphasis.

The midrange opens up with greater image scale and coherence. Voices and instruments sound continuous and organic, with improved separation but no artificial spotlighting.

Bass response tightens and accelerates. Low frequencies start and stop with greater precision, improving rhythmic clarity and system control. Loudspeakers feel easier to drive, maintaining composure at higher levels without strain.

The result is not a different sound.
It is a more complete one.

Why Choose TriCore Ultra

Speaker cables operate under real electrical load.
Any resistance, interaction, or instability introduced here limits what the system can deliver.

TriCore Ultra is built for systems where control, balance, and signal integrity matter more than voicing or effect.

It is designed for listeners who want greater system composure under dynamic demand, improved resolution without brightness, natural midrange tone without added warmth, and tighter, faster bass without weight inflation.

By combining silver, UP OCC copper, and silver plated copper, TriCore Ultra unites refinement, midrange focus, and fast, controlled bass within a single, coherent geometry.

Because once energy and information are restricted between amplifier and loudspeaker, they cannot be recovered.

That is the line.
