Introduced 2023$1,349 MSRP
The OCK-2S is LHY Audio's high-precision reference master clock generator, built around a selected SC-cut OCXO and offering six isolated 10 MHz outputs (three sine-wave, three square-wave) to synchronize DACs, transports, and USB bridges with 50/75Ω clock inputs. LHY Audio is a sister brand of CD-transport maker Jay's Audio, and the OCK-2S sits above the brand's earlier OCK-2 model reviewed by 6moons.
