NUTUBE TECHNOLOGY
The Character of Tubes. A New Perspective.
At the heart of NEON SE lies Nutube — a new-generation vacuum tube technology that brings the distinctive character of tube amplification into a compact, modern design.
Unlike conventional vacuum tubes, Nutube uses a microfabricated fluorescent-display structure to achieve vacuum-tube operation in a smaller format with low power consumption. This opens new possibilities for integrating tube technology into carefully engineered audio circuits.
In NEON SE, Nutube is at the core of an analog design philosophy that combines the expressive qualities associated with tube circuitry with the precision of modern engineering.
The objective is not to recreate the past, but to explore what tube technology can offer when it is approached with a contemporary mindset.
Classic tube principles. Modern engineering. The NERENEAS approach.

CUSTOM NERENEAS NUTUBE MOUNTING
Designed to Minimize Microphonic Interference
Vacuum-tube technology demands careful attention not only to the electrical circuit, but also to the mechanical environment in which the tube operates.
Like other vacuum-tube devices, Nutube can be sensitive to mechanical vibrations, which may produce unwanted microphonic effects in the audio signal.
To address this challenge, NEON SE incorporates a custom-designed NERENEAS mounting socket, developed to help reduce the transmission of mechanical vibrations to the Nutube.
This purpose-built mounting solution reflects our approach to audio engineering: every detail matters, including the mechanical interface between a sensitive active component and the structure that supports it.
Mechanical precision. Vibration control. Thoughtful engineering.
In NEON SE, the Nutube mounting system is more than a support structure. It is part of our commitment to carefully controlling the conditions in which the audio circuit operates.
Capless Master Repro™ Architecture
“Inside NEON SE — Precision in Every Circuit”
Nothing Between You and the Music
At the heart of NEON SE lies our Capless Master Repro™ topology — a proprietary NERENEAS design built around one uncompromising principle: eliminate coupling capacitors and transformers from the audio signal path.
No coupling capacitors. No transformers. No unnecessary barriers.
By removing these components from the signal path, NEON SE embraces a direct, carefully controlled analog architecture designed to preserve signal integrity, transient accuracy, low-level detail, and the natural expression of musical dynamics.
Built around Nutube and supported by our proprietary DC servo technology, Capless Master Repro™ combines the distinctive character of tube amplification with the precision of modern analog engineering. The DC servo helps maintain electrical stability by correcting DC offsets, supporting the operation of this direct-coupled architecture without compromising its signal-path design.
Nothing added between the performance and the listener.

Dedicated Power Architecture — Silentio Inside
A high-performance analog circuit deserves a power supply engineered to the same exacting standards as the signal path itself.
SILENTIO power board — ultra-low-noise architecture
NEON SE is powered by SILENTIO 305, a dedicated linear power supply designed around a dual-stage architecture and three-stage filtering, with a singular objective: provide the audio circuitry with clean, stable, low-noise power.
Rather than treating the power supply as a secondary component, NERENEAS approaches it as an integral part of the overall analog design. Careful power conditioning helps establish the stable electrical environment required for the circuit to perform as intended.
Clean power. Stable operation. A carefully controlled noise floor.
SILENTIO 305 employs LT3045 positive-voltage regulators and LT3094 negative-voltage regulators, providing precision regulation for the corresponding supply rails.

These ultra-low-noise regulator devices are selected for their ability to combine low output noise with excellent power-supply performance. Integrated into the SILENTIO architecture, they support the delivery of clean, stable supply voltages to the NEON SE analog circuitry.
Every stage of the power supply serves a purpose: filtering unwanted disturbances, regulating the supply rails, and maintaining the electrical conditions on which consistent analog performance depends.
SILENTIO 305 — engineered for low noise, built for analog precision.
Inside NEON SE
The internal architecture of NEON SE reflects a design philosophy in which every component, connection, and mechanical detail has a defined role.
Inside NEON SE — designed for symmetry, silence, and precision
The layout is carefully considered to support stable operation, effective noise management, and the integrity of the analog signal path. From the integration of the Nutube circuitry to the dedicated SILENTIO power supply, each subsystem is part of a coherent engineering approach.
Rather than treating individual components in isolation, NERENEAS approaches the entire assembly as one integrated system — where circuit design, power delivery, and physical implementation work together.
One architecture. Carefully considered at every level.
Designed and hand-assembled in Romania, NEON SE brings together proprietary engineering and meticulous construction in a preamplifier built around a clear principle: nothing is incidental.
