First my apologies if this has been covered elsewhere. I want to build a high quality selection of FLAC music files on my NAS drive, to send to my DAC connected to my hi-fi system. Firstly, how do people save files in a database where you can access a particular work, and from that select or play particular movements? What software and catalogue method is used please? Secondly, how do you stream/send it to your hifi? Sonos can't stream FLAC files. I can run my web connection through the power sockets to enable an ethernet connection to my hi-fi but my DAC doesn't have an ethernet socket. So, what equipment do I need to add to enable me to play FLAC files through the hi-fi - which is in a different room from my main computer and wi-fi router? Any thoughts or advice please?
