I'm looking at a RPi for for $60, but then I have to get a DAC which looking around seems might be more than the cost of the RPi.
Some folks are using USB DACs to get high quality analog (or optical) audio from their Pi. But they are not doing it with XBMC, as there are issues with ALSA on the Pi. They are using other software, like Volumio. For the Pi, with OpenELEC or any other XBMC, you really are stuck with using an HDMI audio extractor such as
this. I have used one of these and it performs brilliantly, but the price is high. Good USB DACS can be obtained for much less.
I think Volumio on the Pi with a $10 USB DAC is a very good value solution if you want a basic network music player. If you pay $35 for the audio extractor so you can use OpenELEC/XBMC, its still a decent value IMO, but your cost is getting up closer to $100 when you add the power supply and SD card, so maybe it depends on what you have laying around. I prefer the slickness and options of the XBMC web interface and other available control apps, but in the end Volumio gets the job done, and is easier to get set up to start with.
If you have an HDMI input on your AVR, it becomes a no brainier IMO, the Pi serves as a great network music player with either software you choose.
BTW, I only have used wired Ethernet on mine. You could add a wireless USB adapter to either solution for and additional $10 or less.
