Fidata review here:
This is a fairly new product that I thought you might like to know about.
I have been using one for the last 6 months and I am very impressed. It's expensive (£5900) but costs less than the top flight Melco. It sounds very open and natural.
USB output to a DAC. Ethernet input from router and out to network audio player. Overall plan dimensions exactly the same as Lumin A1/U1/S1 streamers. On off button on the front panel with white led. Brushed silver. Case made from thick plates of aluminium. It looks classy and sounds amazing.
