I have an old sonos system which I'm looking to replace with HiFiBerry. My current set up is a home server (debian NFS or SAMBA shares) with my music as flac files, and good quality amp & speakers. I'm seeking to maximise audio quality.
Though I'm rather confused at the different available hardware. I'm thinking of purchasing the DAC2 HD and a DSP, plus case & power adaptor. Is that all that's necessary?
