Using Soundlink Silver‑Plated Copper Litz Wire in the Bool Audio Clear Wave Unipivot Tonearm

Overview

This article explains how Soundlink silver‑plated copper litz wire works in a high‑end tonearm, why it’s a good fit for the Bool Audio Clear Wave unipivot, and what sonic changes you’re likely to hear when upgrading from a traditional copper‑or‑copper‑and‑silk loom.

At its core, this is about signal integrity at the cartridge level: how the wire’s material, geometry, and insulation interact with mechanical freedom at the pivot, and how that translates into resolution, noise floor, and overall “feel” in your system.

Soundlink Silver‑Plated Copper Litz – What It Really Is

The wire you’re using is a high‑purity copper litz conductor, with each strand silver‑plated and insulated with enamel, then bundled into a very thin, flexible cable. It’s the kind of wire typically used in IEMs and hearing‑aid leads, where tiny microvolt‑level signals and mechanical flexibility are critical.

Importantly, the underlying litz core is Estron brand (ESW‑type litz), supplied to you via Soundlink, a specialist in hearing‑aid and IEM accessories. Estron’s litz is designed for extreme‑low‑signal medical and audio applications, while Soundlink offers it pre‑tinned and ready‑to‑use as well as in 10M packs in variours colours.

This means:

• You’re working with a very small, extremely flexible conductor.

• The wire is electrically excellent but physically delicate – the thin enamel and fine strands are easy to nick or over‑stress if handled roughly.

Key specs at a glance

• Conductor base: High‑purity copper, silver‑plated on each strand.

• Construction: Litz, many fine strands with double‑enamel plus outer jacket.

• Outer diameter: Around 0.4 mm, making it extremely thin and supple.

• Insulation: Enamel‑coated individual strands, plus a coloured outer sheath for easy identification.

• Handling note: This is a precision component, not a rugged cable. It can be damaged by sharp bends, abrasion, or pulling too hard.

Why This Wire Works So Well in a Uni-Pivot Tonearm

Litz wire minimises skin and proximity effects by using many small, insulated strands. Silver‑plating improves surface conductivity and reduces the tiny losses that can accumulate at high frequencies. The upshot:

• Low resistance over the short tonearm run, so more of the cartridge’s tiny signal actually reaches the phono stage.

• Low inductance and loop area, helping cartridge loading and high‑frequency response stay close to design intent.

• Flexible, low‑stiffness loom, which is ideal for a unipivot where the wiring should add as little restoring force as possible.

At the same time, the wire is not robust. The thin enamel and small strands can be damaged by abrasion, sharp bends, or tension. In practice, this means

• Gentle curves and slack are far more important than “pulling it tight”.

• Minimal heat when soldering protects the enamel and keeps the bundle intact.

• Once installed, the wire should be treated like a precision internal component.

Soundlink vs. Older Copper/Silk Litz

Many tonearms use enamelled copper litz with a silk or textile sleeve around it. The silk can feel more robust to the hand, and offers a certain mechanical damping character that some listeners describe as “softer” or more forgiving.

By comparison, the Soundlink / Estron loom offers:

• Silver‑plated litz for better surface conductivity and controlled, stable geometry.

• Modern enamel insulation on each strand, with a thin polymer jacket, giving a more controlled, clinical feel.

• Less mechanical “give” than a loose silk‑sleeved bundle, which can translate into a slightly more immediate, explicit sound, with better channel‑to‑channel consistency.
  
  

The trade‑off:

• More demanding to handle – the wire is delicate and needs careful installation.

• Less forgiving of sloppy routing, tension, or soldering, which can undo much of the benefit.

In the Bool Audio Clear Wave Unipivot

The Clear Wave unipivot is built around low‑effective‑mass and minimal friction at the pivot. The tonearm is designed so that the internal wiring doesn’t add restoring forces or stiffness that could interfere with tracking or freedom of movement.

Using Soundlink‑supplied, Estron‑brand litz fits that philosophy perfectly:

• Very low‑mass, ultra‑flexible loom that doesn’t “tug” on the arm.

• Consistent geometry and controlled capacitance, which helps keep the phono stage’s loading and the cartridge’s own characteristics where they’re supposed to be.

Key points for the Clear Wave installation

• Wires are routed with gentle curves and enough slack so the arm’s movement doesn’t stretch or compress the bundle.

• Solder joints at cartridge tags are kept short and low‑heat, to protect enamel and fine strands. 

• Wires are enclosed in to PTFE tubing  at the cartridge tags. 

• Cartrige tags are crimped on to the PTFE tubing to act as a much needed strain releif for the tiny wires. 

• The loom is not meant to be “worked hard” – repeated sharp bends or tension can damage the delicate bundle over time.

What You’re Likely to Hear

Swapping an older copper or copper‑and‑silk loom for this modern silver‑plated litz tends to bring:

• Lower noise floor: Less hum, hiss, and crackle, especially in revealing systems. The tighter geometry and better insulation help keep micro‑interference and poor contact to a minimum.

• More micro‑detail and separation: The low‑resistance, well‑controlled geometry makes low‑level cues and spatial information more apparent. You often hear more “around” the instruments, rather than just “on” them.

• Tighter, more articulate bass: Better channel balance and grounding can make bass feel cleaner and more precise, with less “blurring” of individual notes.

• A slightly more “open” or explicit flavor: The looser mechanical damping of the litz and the tight electrical control can make the sound feel a touch more immediate and direct compared with older, silk‑damped designs.
  
  

Because the wire is so delicate, the best‑case scenario only happens if it’s installed with care. Poor routing or rough handling can bring micro‑crackle, noise, or even intermittent drops in output, which will quickly overshadow any of the improvements.

A Few Words of Caution

Even though the Clear Wave is a robust tonearm, the internal wiring here is not robust. It’s a fine, high‑precision litz loom, not standard hookup wire. If you’re installing or re‑routing it, go gently:

• Use gentle curves and enough slack.

• Avoid sharp bends, kinks, or pinching near the pivot or tube walls.

• Take care when soldering: keep the heat low and respect the thin enamel.

If that’s done, the Soundlink / Estron loom acts as a genuine upgrade: a low‑resistance, flexible, precision‑engineered path from cartridge to phono stage that supports the Clear Wave’s design intent and can bring a noticeable improvement in detail, clarity, and freedom of movement without fundamentally changing the character of the tonearm.

Availability of the Clear Wave tonearm

The Clear Wave tonearm is available from Cymbiosis Audio in Leicestershire, which has demo units on hand for performance comparison. Contact them at 

enquiries@cymbiosis.com.

The arm does not include Soundlink wire as standard due to its fragile nature, though it's available as an optional upgrade. Current limited production runs only use the standard silk-insulated litz wire.
