I couldn't find a better title and I am not even sure if this is a right sub-forum but here it goes:
I have a decent vintage stereo system in my living room. As source I have an extensive library of mp3 and FLAC files with an external DAC between my HTPC and stereo system. Overall, I am pretty satisfied with this system and its sound.
Now, what I would like to do is to be able to listen to my digital library (served over UPNP) in my bedroom thru a set of headphones. No speakers needed as it is going to be strictly a headphone listening station.
I was thinking about Raspberry Pi plus DAC plus headphone amp but that's three devices and space on my night table is small (also this solution does not have any WAF).
So what are my options here?
