    D1 DAC
    The D1 uses the ESS ES9018 DAC, which is well regarded for its low noise and high fidelity. Due to the high signal-to-noise specs of the ES9018 and the added benefit of double redundancy power source conversion and filtering, the D1 presents impressive low noise and low distortion characteristics. The D1 can process digital audio at any bit depth up to 24-bits and any sample rate up to 96kHz (192kHz using optical)
    D1 Headphone Amplifier
    The D1 includes the ES9601C SABRE headphone driver amp with circuit protection and is designed for a wide range of headphones that will satisfy even the most critical listeners.
    D1 Power
    The D1 is powered directly from the USB input and passed through two stages of regulation to ensure no USB power variations affect the audio quality. Because of the efficiency of the D1, it can even be powered by a phone or tablet.
    D1 Preamp
    The audio line-out preamp connects to powered speaker systems, amplifiers, or other external decoders with an analog or optical output.
    D1 Volume Control
    Volume for headphones and line-out is controlled directly from the D1 front panel via the digitally-controlled analog potentiometer. Smoothly adjust volume levels at fine increments without any undesirable noise or channel imbalance at lower volumes.
