The Chord Hugo 1 vs the Chord Hugo 2: What are the differences?

I had a good time visiting the Chord booth at CanJam this year. The two British gents including sales manager Colin Pratt were very amicable, even a bit entertaining as far as booth-side stop-and-chats go. They have a lot to be happy about. Chords move into portable/transportable DAC/Amps has been a swift and successful one.
