• • Elevate Your Raspberry Pi to True Hi-Fi Standards

    The LHY Audio RPI takes the versatile Raspberry Pi 4B platform and re-imagines it for the high-end audio world. While a stock Raspberry Pi is a powerful streamer, its performance is often limited by noisy switching power supplies and high-jitter onboard clocks. LHY Audio solves this by integrating a laboratory-grade power system and a high-precision timing core into a single, shielded aluminum chassis.

    Key Features:

    • Precision OCXO Clock Upgrade: We have bypassed the Pi's standard crystal oscillator in favor of a high-precision Oven Controlled Crystal Oscillator (OCXO). This significantly reduces digital jitter, resulting in a more focused soundstage and smoother high frequencies.

    • Integrated Linear Power Supply (LPS): Features a custom-made Talema toroidal transformer and LT3042 + PNP ultra-low noise regulators. This provides the Pi with the stable, clean DC current it needs to perform without electrical interference.

    • EMI/RFI Shielded Chassis: The entire unit is housed in a thick, CNC-machined aluminum enclosure, protecting the delicate audio signal from external electromagnetic interference and providing excellent heat dissipation.

    • Ready for Any OS: Fully compatible with your favorite audiophile operating systems, including RoPieee, Volumio, Moode, and DietPi.

    • External Clock Support: Includes a 10MHz BNC input, allowing you to sync the RPI with a master clock (like the OCK-1 or OCK-2) for even higher performance.
