A well-designed power supply is the foundation of good sound. And what is good for sound quality are linear power supplies, with their greater, high-quality, and stable voltage output, smaller ripple, and lower noise. The PL50, being a high-quality linear power supply, brings to your sound a lower noise floor, more refined dynamics and transients, and a more accurate, warmer tone to lower frequencies.
Features:
Toroidal transformers by their very nature have numerous advantages, allowing them to be very efficient. This is due to the coils in the transformer not having a set angle at which they are bent, leading to a more uniform magnetic field and less magnetic flux leakage. Inside the PL50 is a custom 50VA audiophile-grade toroidal transformer, made of high-quality Nippon Steel iron and high-purity oxygen-free copper wires for higher efficiency, higher precision, more stable voltage, and for higher energy output.
High-quality parts were chosen for every part of the design for higher and more reliable performance - such as the Shindengen bridge rectifier, Tl voltage regulator, and Nippon Chemi-Con and Rubycon capacitors.
The clear digital display distinctly shows the current-voltage, letting anybody easily know what is happening with the power supply. The PL50 supports both 12V and 15V outputs, allowing it to match the voltage requirements of various FiiO devices.
