Amazon Echo Link - Hi-fi?

Amazon rolled out a new "hi-fi" streamer, Echo Link, that allows you to stream audio from your Echo to your stereo. It's $200, so not on the cheap end for Amazon (they have a cheaper Echo Input for $35) but definitely significantly cheaper than BlueSound or other streamers out there. It looks pretty sleek.

I can't seem to find any specs on the DAC chip or any components. Anyone hear anything about this? Thoughts on how this would sound?
