Product Description
The foundation of high-performance audio is clean power. To cut costs, many devices use internal switching power supplies that introduce noise, creating a bottleneck for sound quality. The LHY LPS-15 is a 15W linear power supply designed to address this issue at its source. It delivers exceptionally clean and stable DC output, unlocking the full potential of your sensitive audio equipment. By eliminating power-borne noise, it reveals a blacker background, greater detail, and a wider soundstage—all at a benchmark cost-performance ratio.
Low Noise & High Performance: Compared to switching power supplies, this linear power supply reduces DC output noise by several orders of magnitude (ripple as low as 17.28μV, with some data mentioning 20μV). It effectively filters out grid interference, delivering cleaner and more stable current.
Premium Components: Utilizes imported high-quality HiFi audio components, such as Talema sealed toroidal transformers, LM1085 voltage regulator chips, and Japanese electrolytic capacitors, ensuring high performance and stability.
Safety & Heat Dissipation: Features a one-piece aluminum alloy casing for enhanced heat dissipation and includes components like TYCO self-recovery fuses to ensure safety and stability during prolonged operation.
Wide Compatibility: Suitable for various externally powered audio and digital devices, including Raspberry Pi, CHORD Qutest DAC, and speaker systems.
