LHY OCK-1S Reference Master Clock Generator
Taxes & Shipping Included
The LHY OCK-1S is a high-performance master clock generator designed to elevate the timing accuracy of your digital audio system. Engineered with LHY Audio’s renowned attention to detail, the OCK-1S delivers ultra-low phase noise, enhanced jitter control, and a rock-solid frequency reference—unlocking greater musicality, clarity, and coherence from your digital chain.
Housed in a compact yet robust chassis, the OCK-1S uses a premium OCXO module, low-noise linear power supply architecture, upgraded voltage regulation, and high-quality clock distribution components. Whether used with DACs, network switches, DDCs, or digital transports, the OCK-1S brings a refined, analog-like ease to the sound while improving detail retrieval and imaging precision.
The LHY OCK-1S is ideal for listeners who want to take the next step in digital refinement without jumping to flagship-level pricing. It is designed for:
- Digital Audiophiles Building Their First Clocked System – Users who are new to external clocking and want to unlock the performance potential of devices like the LHY SW-10, LHY FMC, mid-level DACs, DDCs, and streamers.
- Systems Where Precision Timing Creates Clear Gains – If you use networked playback (Roon, UPnP, streaming), reclockers, or digital transports, the OCK-1S can dramatically improve timing accuracy.
- Those Seeking Maximum Value-to-Performance – It delivers much of the refinement of higher-priced clocks while remaining accessible, making it an excellent gateway into high-end master clock performance.
- Users Wanting a Natural, Smooth, Analog-Like Presentation – Its OCXO-based design provides a relaxed yet detailed sonic character that pairs beautifully with both analytical and warm systems.
