My 2 cents

I experience no problem with DSD (.dsf) with my Odroid C1+ RuneAudio (original buid or latest build), same with volumio, but I need to compile a special MPD package with Archphile.
The only problem I have is pops and clicks with Runeaudio (FLAC 24/192), no problem at all with Volumio 1.55.1 and some problems with Archphile.
I suppose the differences between the software solutions depend on what kernel and/or what MPD versions they are based on (event if Rune/Archphile are based on Archlinux and Volumio on Raspbian/debian)
