A high-performance DAC series model with a powerful headphone amplifier function and support for 3 Hi-Res audio inputs.
This D/A converter and headphone amplifier product supports Hi-Res audio sources and is USB bus-powered, employing an ESS Technology "ES9023P" DAC IC and a Cirrus Logic "CS8416" digital audio receiver.
Experience the sound quality of a high-performance DAC with a coupling-less design that delivers a straight, uncolored, high-fidelity sound close to the original, creating a realistic experience as if the performance were happening right in front of you.
In addition to USB, it features SPDIF optical input and coaxial input terminals, allowing you to switch between three digital inputs.
The headphone amplifier uses a two-stage configuration with three operational amplifiers, and the current amplification stage is configured independently for the left and right channels, achieving high-quality sound with excellent channel separation and high-power output capable of driving high-impedance headphones.
