X-3

Precision-engineered 10MHz master clock for ultimate digital timing accuracy.

The Soulnote X-3 represents a breakthrough in clock generator design, born from a singular focus on eliminating the timing errors that compromise digital playback. By providing a stable, high-precision 10MHz reference signal, it allows compatible DACs and transports to operate with a level of temporal authority that defines the pinnacle of digital audio reproduction. At the heart of the X-3 is an SC-cut, oven-controlled crystal oscillator (OCXO), selected specifically for its superior stability and remarkably low phase noise. Unlike standard crystal oscillators, this thermostatic bath-type design ensures a constant operating environment for the crystal, resulting in an output signal of unparalleled consistency and purity. This core technology is supported by a 200VA toroidal transformer—a capacity typically reserved for power amplifiers—ensuring the oscillator receives an abundant and clean power supply. The X-3 is built to a standard that prioritises sonic performance above all else. Every aspect of its construction, from the naked foil resistors to the non-NFB discrete voltage stabilisation circuit, is engineered to prevent the introduction of electronic noise. The result is a profound improvement in spatial imaging, detail retrieval, and naturalness, allowing the listener to experience the true intent and atmosphere of the original recording.

Key Features

01

SC-Cut OCXO

Features a thermostatic bath-type crystal oscillator for unprecedented frequency stability and ultra-low phase noise.

02

High-Capacity Non-NFB Power Supply

Utilises a massive 200VA toroidal transformer and ultra-high-speed SiC diodes to deliver clean, agile power to the oscillator.

03

Quiet Power Domain

Unnecessary circuits, such as LEDs and relays, are stripped from the oscillator domain to ensure an entirely noise-free environment.

04

Precision Naked Foil Resistors

Employs custom satellite-grade naked foil resistors in the output stage to minimise thermal noise and maintain signal integrity.

05

Anti-Vibration Chassis

Features a dual non-rigid top plate and spike supports placed directly under the transformers to dissipate mechanical vibrations.

Engineering Philosophy

Chapter 01

Engineering Philosophy

The X-3 is based on the discovery that standard clock generation often introduces subtle timing fluctuations that the human ear interprets as a loss of realism. By creating a super-quiet power supply domain and ensuring the crystal oscillator is isolated from all electrical and mechanical interference, Soulnote has produced a clock that preserves the subtle temporal cues essential for a holographic, three-dimensional soundstage.
Build and Materials

Chapter 02

Build and Materials

The housing design is a testament to Soulnote’s refusal to compromise. The unit features non-rigid AC inlets, titanium washers, and carbon dampers, all working in concert to expel internal energy without dampening it. This non-fixed structural approach ensures that the oscillator operates without being influenced by external vibrations, resulting in a cleaner and more stable frequency output.
Listening Notes

Listening Notes

When integrated into a high-end system, the X-3 provides an immediate sense of ease and naturalness. Listeners will observe a darker background, more precise instrument placement, and an improved sense of air around performers. It does not alter the tonal character of the system; rather, it removes the digital 'veil', allowing the music to flow with greater rhythmic conviction and emotional depth.
