[ The Copper Ladder ]

Copper in audio is not a single material category. It exists as a progression of different manufacturing philosophies and structural designs, and each represents a different way of controlling signal behavior.

-

■ Standard Electrolytic Copper ( )
Industrial-grade copper used in general electrical applications.
Stable, functional, and widely available.
Structural behavior is conventional and consistent with mass manufacturing processes.

■ Oxygen-Free Copper ( )
A refined copper with reduced oxygen content.
One of the most commonly used materials in audio cables.
Typically associated with:
- improved material uniformity
- reduced internal variability
- slightly clearer transmission behavior compared to ETP

■ PC-Triple C (Furukawa Electric)
A structural processing approach to copper conductors.
Focuses on forming continuous crystal structures through specialized mechanical processing.
Commonly associated with:
- smoother continuity in signal flow
- reduced structural interruptions from drawing processes
- improved coherence in signal behavior under load

■ (Mitsubishi Cable Industries)
A precision-grade copper conductor system.
Emphasizes controlled material processing and high manufacturing consistency.
Often associated with:
- stable transmission behavior
- uniform conductor characteristics
- reliable performance in high-resolution audio systems

■ (Ohno Continuous Cast Copper)
A major structural development in conductor manufacturing.
Produces long, continuous crystal formations with reduced grain boundary interruptions.
Commonly associated with:
- high signal continuity
- stable signal transmission behavior
- improved preservation of low-level information

■ High-Purity Copper ( )
Very high purity copper used in specialized applications.
Focuses on reducing microscopic impurities that can affect signal integrity.
Often associated with:
- improved micro-detail retrieval
- clearer spatial definition
- reduced background interference

■ Ultra High-Purity Copper ( )
One of the highest commercially achievable purity levels.
Represents the extreme end of conventional copper refinement.
Commonly associated with:
- high transparency of signal transmission
- preservation of fine micro-information
- minimal material-related interference

■ ™ (Dia Ultra Crystallized Copper – Mitsubishi Materials)
A structurally engineered copper system developed through controlled crystallization processes. Unlike conventional conductor classifications based primarily on purity, DUCC™ focuses on internal structural uniformity and boundary stability under dynamic conditions.
Often associated with:
- stable low-frequency behavior under dynamic pressure
- improved transient consistency in dense musical passages
- coherent spatial structure during high-energy playback
- reduced structural variability in signal transmission

-

For decades, conductor development has largely pursued the same objective: fewer impurities, greater consistency, and higher levels of refinement. But eventually a question emerges: If copper has already approached the practical limits of purity, where does advancement come from next?

The answer, for some engineers, lies not in purity itself, but in how the structure carrying the signal behaves under load.

-

Next up, we'll take an in-depth look at one of the most sought-after conductor materials in the modern high-end audio world – DUCC™, developed by Mitsubishi Materials, Japan.

[ Why Copper Conductors Don't All Sound the Same ]

At first glance, copper should behave identically in every audio cable. Same metal. Same function. Same purpose. But in real-world listening, experienced audiophiles consistently report otherwise.

Differences emerge not because copper "adds" sound, but because it does not transmit all signals with equal structural consistency. As an electrical signal travels through a conductor, it is affected by:

- internal grain behavior
- structural continuity
- microscopic transmission stability
- interaction between material boundaries

These factors don't change the music. They influence how intact the information remains while it is being carried. Which is why perceived differences often show up as:

- clarity vs density
- spatial openness
- separation of instruments
- stability during complex passages

Not tonal coloration, but transmission behavior.

Copper is not just a conductor.
It is a controlled environment for signal travel.
Types of copper does not change the music.
It changes how much of it survives the journey.

Coming up next, we'll explore the copper conductor hierarchy:
ETP, OFC, PC-Triple C, PCUHD, OCC, 6N/7N, DUCC™

We'd like to thank everyone who joined us at the official Taiwan reveal of the Four Winds.

It was a rare opportunity for us to meet our supporters face to face, and to witness firsthand the excitement, curiosity, and quiet astonishment upon hearing the Four Winds for the very first time.

With the Four Winds finally standing alongside the First Light, R&W's philosophy of "live auditorium sound" suddenly became something beyond words, no longer needing explanation, only experience.

The eureka moment.

Today, audiophiles in Taiwan joined the growing worldwide acclaim surrounding the Four Winds. We would also like to extend our sincere thanks to for organizing the event, as well as Lady herself for her appearance and signing session.

Thank you all for being part of this chapter with us.

-

The Second Chapter preorders for Four Winds will open soon.
With only a limited number of special edition sets left worldwide, this will likely be the final opportunity to claim one before the chapter closes.

Official announcement forthcoming.

“The mistake was treating the Four Winds like it was supposed to reproduce my preferred seat at the performance. But the Four Winds is not changing the music. It is changing your position inside the music.”

— D. Wolff, First Chapter, Four Winds 001, USA
R&W First Class VIP 033

Mr. Wolff placed his trust in us when Four Winds was still in its infancy, before its final form was fully defined, and is among the very first First Chapter supporters. For that early belief, we are honored to present him the 001 build.

He selected a distinctive DU/ALITY configuration:

Left: [ ] + Lumi / Iridescent
Right: [ ] + Doomsday Scarlet

Drawn from the Four Winds in the Book of Revelation, these are not symbolic names, but expressions of two opposing functions within the same system.

[ VIGILIA ] corresponds to the force that restrains — holding structure, preserving order, maintaining stillness. [ APOCALYPSE ] corresponds to the force that releases — breaking structure, dissolving order, allowing irreversible change.

Together, they define the core principle of the Four Winds:
not harmony through balance, but restraint of opposing forces.

We are grateful for early trust like this, which helped shape the Four Winds in its most formative stage.

We look forward to sharing more personalized builds from our First Chapter supporters as this series continues.

*Lastly, as one who appreciates soundstage, Mr. Wolff's favorite pairing with the Four Winds is our beloved .

Four Winds — Artist Introduction

First, our sincere thanks.
Support for the First Chapter of Four Winds has exceeded our expectations. The Second Chapter will soon open for preorder, with its own unique options.

For this project, we also wished to celebrate a form of artistry seldom highlighted in the world of audio: the craft of hand-painted nail art.

Across the industry, collaborations between IEM makers and nail artists have quietly produced some of the most intricate miniature works in our field. With the Four Winds, we are honored to continue that tradition.

Our collaborating artisan, , has spent nearly a decade devoted to both nail artistry and education. Known for her delicate work and attention to detail, each brushstroke is composed within the tiny canvas of the nail. Her philosophy is simple:

"Treating even the smallest canvas as a true work of art."

For the Four Winds, that discipline finds a new surface,
extending from the fingertip to the artwork inserts.

Cypress T. | The Face of

Following LUA GaZe, we are honored to collaborate once again with Taiwanese artist Cypress T. as the character model and embodiment of VaNa.

Cypress shares many of the qualities that define the Lady of the Lake: quiet presence, emotional depth, restraint without distance, and a calmness that draws others inward rather than demanding attention.

Raised through music and art, Cypress approaches creation not through force, but through flow, allowing emotion and intuition to guide her process naturally.

In both appearance and spirit, she became the natural human reflection of VaNa: serene yet luminous, gentle yet quietly certain, carrying an allure that feels intimate without ever losing its sense of reverence.

Her likeness and presence became inseparable from VaNa herself, allowing her to emerge not merely as a design, but as a presence that could almost meet the listener face to face.

LUA VaNa | THE INSPIRATION

"Narrative tuning" is the heart of 's design philosophy.
It is not the use of a story merely as inspiration, but the full extraction of its emotional and structural logic, reconstructed into sound, form, and presence.

In , this logic becomes material.

Drawn from forest and water, its palette holds in quiet green. Silver moves across the surface as light and motion, while gold appears where light breaks through.

VaNa rises with Excalibur. The blade catching gold as it emerges, silver ripples spreading and falling away in droplets.

The same logic governs sound.

Like a forest lake at rest, space opens wide and unforced, water cool against the skin. Nothing to follow, nothing to chase.

Voices come gently into focus, like VaNa herself rising from still water, unhurried, luminous, and quietly certain, as though she has chosen to meet you.

And in that meeting, something older begins to surface...

-

VaNa: The Waters That Remember

In the old Arthurian legend, there is a presence who does not rule, yet shapes the fate of kings: the Lady of the Lake.

From still waters and ancient woods, she emerged to offer King Arthur the sword Excalibur — a symbol of rightful power, entrusted rather than possessed.

In time, the waters would call the blade home once more. Not lost, but received, as though it had always belonged there. Between these moments lies a quiet truth: that power, in its purest form, is never truly held, only entrusted and released.

Some say the Lady had no name. Others believe it was simply forgotten. But in quieter tellings, she is remembered as VaNa — from an ancient word meaning "forest," where still waters and ancient woods exist as one, inseparable and enduring.

She remains there still, not as ruler or keeper, but as part of the lake itself.

Calm, present, unbroken within her domain.
