Unfortunately I'm not tech savvy enough to determine whether this diminutive PC can be configured to act as a music server, but for $299 it's relatively cheap, so perhaps a computer literate thread reader could take a look and comment as the form factor is good - http://www.indiegogo.com/projects/tango-pc-worlds-most-powerful-pocketable-dockable-gameable-officeable-pc
Lots of you asking what to use as a streamer ... I'm thinking I'll try CAPS server computer to begin to ensure I get the best sound, and if that works well, then perhaps a small notebook. I just don't know of anyone who makes a small, portable streamer with full 24/192 let alone DSD that's not PCM converted. Perhaps in 6 months that will change...until then, I'm off to read up at Computer Audiophile to build a decent music server.
Would be nice if A&K used their new 240 as a basis to make a player-only model with digital out and no AMP/DAC...that would be ideal, but I doubt anyone will, since most people want an all-in-one. It's really up to Chord to do this: matching chassis to the Hugo, 512 GB capacity with an SD card, full native DSD, upgradable firmware and perhaps networking ability to download high res music via Bluetooth. I'm sure people would pay $1,500+ for the right device, built to Chord's high standard.
