DIGIONE SIGNATURE PLAYER

Does anyone use this streamer? Seems like an amazing bargain but not a plug and play type of devise on the surface. If you are using it what is your configuration? MAC/PC based? Digione OS? Music software? Do you know what OS's work with what music software? I'm familiar with JRiver and Foobar, nice to have it controlled through a tablet or phone. Can't find much info on the net regarding this relative to this product.

What is the best connection to the DAC? USB or COAX?

Any help appreciated!
