AK4493S DAC & XMOS XU208 USB Interface

The DX1 features the brand new AKM AK4493S DAC chip. This ensures a precise and musical conversion, while allowing, in association with the USB XMOS XU208 interface, the support of high resolution audio streams, up to PCM 32bit 384kHz and DSD256.

Discrete LNRD

The Topping DX1 uses a discrete LNRD (Low Noise Reference Driver) circuit to effectively filter out noise and interference from the USB power supply. As a result, the power supply stage is able to provide the DX1's audio circuitry with a clean and stable electrical signal.
