LHY Audio LPS-50 Pro Linear Power Supply (Ultra Low Noise PSU)

Product Description

Reference-Grade Linear Power for High-End Digital Audio

The LHY Audio LPS-50 Pro is a flagship linear power supply designed to deliver ultra-clean, high-current DC power for demanding audio components.

Built on an advanced low-noise architecture using parallel LT3041 regulators, the LPS-50 Pro significantly reduces electrical noise, improves transient response, and enhances overall system performance—making it ideal for high-resolution DACs, streamers, and digital front-end equipment.

Compared to standard linear supplies, the Pro version delivers lower output impedance, improved current stability, and superior noise suppression—resulting in greater clarity, dynamics, and tonal refinement.

In simple terms: the LPS-50 Pro delivers cleaner, faster, and more stable power than standard linear supplies—allowing your audio system to reveal more detail, dynamics, and realism.

• Network streamers and digital transports
• Premium network switches and reclockers
• Any system requiring ultra-clean, stable DC power

LPS-50 vs LPS-50 Pro

Note: While the LPS-50 shows extremely low ripple in static measurements, the LPS-50 Pro is engineered for superior performance under real operating conditions. Its advanced regulation and lower output impedance provide more stable power delivery during dynamic load changes—resulting in better overall sonic performance.

Who It’s For

• Audiophiles running high-resolution DACs and streamers
• Systems where power quality directly impacts performance
• Users upgrading from standard linear or switching supplies
• Anyone seeking maximum performance from their digital front end
