The Atoll Electronique HD100 Headphone Amplifier is equipped with optical and coaxial S/PDIF inputs as well as a USB type B port.

In the latter case, the supported resolution is limited to 24 bits and 96 kHz, whereas the coaxial input handles PCM streams up to 32 bits and 384 kHz.

The Atoll HD100 is distinguished by a careful design with discrete component output stages and high quality MKP capacitor audio links. This DAC headphone amplifier also benefits from very good manufacturing quality, with a thick steel frame and a brushed aluminum front panel.

The Atoll HD100 headphone amplifier and USB DAC is the ideal partner for high-end hi-fi headphones.
