    D3 Internal Converter
    The heart of the D3 is the AK4396 DAC, which is well-regarded for its low noise and high fidelity. Due to the high signal-to-noise specs of the AK4396 and the added benefit of double redundancy power source conversion and filtering, the D3 presents impressive low noise and low distortion characteristics. The D3 can process digital audio at any bit depth up to 24 bits and any sample rate up to 192kHz. D3 pads (upsamples) all bit depths internally to 24-bits, thus achieving a higher signal-to-noise ratio.

    D3 Headphone Amplifier
    The D3 contains a high-performance headphone amplifier based on the LME49726 low-noise opamp. This amp is able to provide low-impedance, high-fidelity audio and a 2-volt output which easily drives a wide range of headphones, satisfying even the most demanding headphone enthusiasts. The D3’s relay-controlled stereo output can also be connected to any system with an analog audio input, such as Audioengine powered speakers.

    D3 Power
    The D3 is powered directly from the USB bus and power is passed through two stages of regulation to ensure no USB bus power variations affect the audio quality. This low-noise, low-ripple power supply is located on a separate circuit board for extra isolation and thermal management.

    D3 Volume Control
    Volume is controlled from the computer’s OS and is implemented in the D3 as a digitally-controlled analog volume control.
