I'm pretty happy with the rPi portable build and ran into an R2R rPi DAC.

I'm not sure if this can be portable because it akwardly extrudes. If a compact case can be created, then maybe.

Thoughts on specs?

I'm able to control with an IR remote control a la Tera Player so was hoping I can do something similar here.

I'm looking to do something portable like this minus the Hugo2. Just the rPi w/ R2R DAC. Hope a compact case is released.
