D1 USB
The D1 utilizes the TI1020B USB controller, widely recognized as a standard for higher-end USB audio products. The D1 is powered directly from the USB bus and USB power is passed through two stages of regulation to ensure high stability and low noise.

D1 DAC
The D1 uses the AK4396 DAC, 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 D1 presents impressive low noise and low distortion characteristics.

D1 Headphone
The D1 includes a headphone amp based on the TI OPA2134 low noise opamp. This headphone amp is able to provide low-impedance, high-fidelity audio to a wide range of headphones and supports headphones with impedance as low as 20 ohms.
