Thanks for the comments guys! Hmm SlimRio, yes I have used that a few years back. My main niggle was the screen layout was wrong (wrapped lines). It actually looks like the Squeezebox Boom has a very similar screen resolution to the Empeg.

Is the hardware similar between the Empeg and RioReceiver? Makes sense they would be similar. I'm having a hard time finding specs, need to dig around archive.org a bit..
