Acoustic Invader FULCRUM- PreAmplifier

FENCER — More Than a Preamplifier
In a world where sound is often reduced to numbers, graphs, and dry specifications, Fencer steps in as a quiet revolutionary — subtle, yet relentlessly precise. This is not just another unit in the portfolio. It is our flagship deliverable, the pinnacle of development, a synergy of experience and intuition. Simply put — the best of us.
The new, powerful enclosure is not just industrial design, but a platform. Solid, massive, yet elegant — like a chassis that knows how to keep energy under control. Inside, every detail plays its role in that silence between notes.
At its core lies copper-in-oil coupling with JANTZEN AUDIO AMBER Z-CAP capacitors — delivering a natural, fluid signal transfer with no added coloration and no loss of detail, allowing music to remain true to its original character.
A fully balanced architecture ensures absolute symmetry, a quiet background, and effortless dynamic expression.
The entire signal path relies on Furutech connectivity — a no-compromise interface between electronics and reality. Internal wiring follows the Duelund philosophy — not merely conductors, but carriers of character, texture, and emotion.
Control? Pure precision. The four-channel TKD potentiometer operates with surgical accuracy, preserving every nuance without compromise in balance or dynamics.
And then — the power supply. A new hybrid power supply developed exclusively for Fencer. It doesn’t just support the system — it leads it. Stable, silent, yet powerful — like an invisible conductor holding everything together.
And yet… Fencer is not only a technical achievement. It carries a quieter, deeper message.
On its top cover, inscribed in Braille, it reads:
“FEEL THE SOUND AND TOUCH THE MUSIC”
This is not marketing. It is a statement.
This device is an expression of empathy toward people living with different forms of disability — diverse, personal, often invisible. Through a form dedicated to the blind and visually impaired, this message finds its purest expression: sound is not a privilege, but a right. Music belongs to everyone who can feel it.
Fencer does not seek attention. It seeks trust.
And once you give it that — it returns music, exactly as it should be.

FENCER – Flagship by Acoustic Invader
No compromises. No shortcuts. No noise between you and the music.
FENCER is not just a preamplifier — it is the culmination of a design philosophy shaped through years of relentless pursuit of sonic truth. A 20kg statement piece built around an extended JFET topology, delivering ultra-low output impedance and effortless control.
Inside, only the finest: – Jantzen Amber Z-Cap copper-in-oil capacitors
– Furutech rhodium connectors throughout the entire signal path
– Furutech rhodium in the power path as well, via the reference-grade FL-09 connector
– A newly developed hybrid digital-analog power supply with massive current reserves
– Nichicon Muse capacitors at the core of its energy architecture
Every detail is intentional. Every choice serves the music.
The chassis, crafted from high-grade anodized aluminum, is executed with absolute precision — no visible screws, no distractions. A clean, monolithic form that reflects the discipline of supersonic flight.
The top cover carries a deeper message. It is not there merely to enclose the device — but to open it toward people.
Engraved into its surface is a Braille inscription:
“Feel the sound, and touch the music.”
A quiet gesture of respect and empathy toward those who experience the world differently. A reminder that music is not a privilege of sight, but a universal language of emotion — where every tone has texture, and every vibration can be felt.
FENCER doesn’t just reproduce sound.
It builds a bridge between technology and emotion.
