This is very interesting DAC based on 8pcs AD1955 chip & Xmos USB Audio

The sound is very clear with analog taste


1. XMOS asynchronous USB sound card, this is the basic function for all popular DAC for PC

2. FIFO memory cache architecture which is adaptive technology (I think it is interesting point)

3. Audio receiver chip AK4118 with low jitter

4. Adaptive synchronization circuit with up sampling

5. MDCS technology 

6. DCVC (Digital currentVolume control) zero distortion and zero noise volume control circuit

7. Simple I / V conversion and analog filter


Here is the picture:
