Item description

Features
  • Remarkable Sound Upgrade: Instantly enhance your HiFi setup with deeper silence, richer dynamics, and clearer details. By providing ultra-clean, stable DC power, this linear supply minimizes unwanted hum and interference, letting your audio equipment perform at its absolute best.  
  • Professional Noise Reduction: Engineered for precision, with advanced ripple and EMI suppression, it achieves measured ripple as low as 30 µV, over 100× lower than typical switching power supplies. High-frequency interference is minimized, expanding dynamic range and revealing subtle musical nuances.  
  • Wide Compatibility: Perfect upgrade for devices such as DACs, preamps, streamers, routers, and modems. Provides stable, low-noise power for improved clarity and depth across your audio chain, ideal for desktop, bookshelf, and home Hi-Fi environments.   
  • Audiophile Components: Featuring advanced EMI filtering, low-resistance high-current MOSFET output, high-current rectifier bridge, and CLC ripple-filtering deliver ultra-stable, fast-response DC power. Experience exceptionally clean, low-noise sound with rich detail and dynamic precision.  
  • User-Friendly Features: Integrated aluminum chassis ensures excellent heat dissipation. Features LED voltage display, ±0.5 V adjustable voltage, and replaceable fuse. Compact, durable layout delivers long service life, reliable performance, and convenient voltage monitoring for audiophiles.

Warm Tips

1. Due to component availability and stock, internal components may be replaced with equivalent quality parts, without affecting performance or reliability.

2. The power supply has two output terminals but only one regulated circuit, and the two outputs are internally connected in parallel. You can use both simultaneously, but total current must not exceed its rated output current.
