This DAC series high-performance model is equipped with a powerful headphone amplifier function and supports 3-line high-resolution inputs.
A D/A converter and headphone amplifier that uses ESS Technology "ES9023P" and a digital audio receiver that uses Cirrus Logic "CS8416" for high-resolution audio sources that support USB connection bus-powered operation.
The high-performance DAC sound quality is straight and high quality sound close to the original unseasoned sound due to the couplingless design, so you can experience the reality you are playing before your eyes.
In addition to USB, the digital input comes with SPDIF optical input and coaxial input terminals, so you can switch between 3 digital inputs.
The headphone amplifier is a 2-stage configuration with 3 optics amplifier levels are independently configured on the left and right sides for high sound quality and high impedance headphones with good channel separation.
