There's 4 output mode of DX3 Pro: Headphone amp only, Headphone amp + Line out, DAC only, Pre-amplifier. DX3 Pro is suitable for almost all usage scenarios.
DX3 Pro is using XMOS XU208 + 2 x AK4493 + OPA1612 to support up to 32bit768kHz PCM decoding and DSD512 native decoding of USB input. Besides, DX3 Pro has 2 x Coaxial and 1 x Optical input which support up to 24bit192kHz PCM decoding. DX3 Pro also has bluetooth input which support SBC, ACC, APTX, APTX-II, APTX-HD transmission.
We also made efforts on Headphone amp of DX3 Pro. It's output power is up to 1000mW x 2@32ohm load and 125mW x 2@300ohm, which is almost suitable for all headphones. Another point which is worth to mentioning is, output impedance of it is no higher than 0.1 ohm (Probably it will be even lower at retail version).
Stay tuned for more information.
