LHY OCK-2S Master Clock Generator
High-Precision Reference Clock for the Ultimate Digital Front-End
The LHY OCK-2S represents the pinnacle of LHY Audio’s clock engineering — a next-generation master clock generator designed for audiophiles who demand absolute precision, ultra-low jitter performance, and a clean, stable time reference that transforms every digital component in the chain.
Featuring an ultra-low noise OCXO module, premium component selection, isolated outputs, and a dramatically upgraded internal power architecture, the OCK-2S delivers a level of refinement and musical coherence that lifts DACs, network streamers, DDCs, CD transports, and master-clock-compatible devices into a new tier of realism.
Key Features
- Premium Ultra-Low Noise OCXO – A high-grade Oven-Controlled Crystal Oscillator provides exceptional thermal stability and phase noise performance, ensuring timing accuracy far beyond standard crystal clocks.
- Enhanced Power Supply Architecture – The OCK-2S includes advanced linear regulation stages, high-quality LDO regulators, and further-enhanced noise filtration to maximise clock purity.
- Multiple Isolated Outputs – Designed for modern digital ecosystems, it offers several 10MHz outputs (BNC) with galvanic isolation, ensuring clean distribution to multiple devices without cross-contamination.
- Superior Jitter Performance – Clock jitter is minimised to extremely low levels, unlocking improved soundstage depth, transient clarity, and tonal purity.
- High-Grade Chassis Construction – A rigid aluminium enclosure with anti-resonance treatment reduces interference and mechanical noise, preserving absolute clock integrity.
Who Is It For?
The LHY OCK-2S is ideal for:
- Audiophiles seeking maximum realism and holographic soundstage
- Owners of high-end DACs/streamers that accept 10MHz master clock input
- Users who want to upgrade multiple digital components at once
- Systems where every micro-detail and timing nuance matters
- Enthusiasts who already own the OCK-1S and want the next level of refinement
If your digital system is transparent enough to reveal small improvements — the OCK-2S will deliver a big one.
OCK-2S vs OCK-1S — What Makes the OCK-2S Better?
While the OCK-1S is already an outstanding value in external clock generators, the OCK-2S takes performance to a significantly higher level.
Here are the core improvements:
1. Higher-Grade OCXO Module – The OCK-2S uses a superior, even lower-noise OCXO with improved temperature stability and far better close-in phase-noise behaviour — crucial for micro-detail and dimensionality.
2. More Advanced Power Supply – Compared with the OCK-1S, the OCK-2S includes:
- Additional regulation stages
- Lower-noise LDOs
- Larger filtering capacity
- Better rail isolation
This results in a significantly quieter clock output.
3. Cleaner, More Isolated Outputs – The OCK-2S offers improved output isolation, reducing crosstalk when feeding multiple devices and keeping jitter contamination to an absolute minimum.
4. Lower Measured Jitter – Benchmark jitter performance on the OCK-2S is notably superior, yielding:
- Smoother treble
- More stable imaging
- Blacker background
- Improved timing focus
5. More Refined Sound Signature, Users can expect:
- Greater clarity and coherence
- More organic flow and micro-dynamics
- More believable instrument placement
- Increased tonal density
The difference is not subtle — the OCK-2S is tailored for high-resolution systems where maximum performance is the goal.
Summary
The LHY OCK-2S is a flagship-level master clock generator that elevates digital systems to exceptional performance through ultra-low noise clock precision, robust power design, and beautifully clean timing output. For systems capable of revealing fine improvements, the OCK-2S provides a transformative upgrade that clearly surpasses the OCK-1S.
