You could go the mac mini route + itunes + audirvana
I use my imac + itunes + audirvana and have 24/192 capability with remote from my droid tablet using a free app called Retune
Retune reads all of the itunes playlists, albums, genres etc... - so it functions the same as itunes
If I changed my dac to something of higher resolution then the associated driver would take care of linking at that resolution
It really is future proof since everything is software controlled
Audirvana streams the actual music file and I have it configured not to upsample, because the Schiit Bifrost dac I have sounds better that way
Hope this helps
