Let me start by asking if a raspberry pi has any sonic improvements over a fully functional small pc? Currently I am using a Marantz AVR as a dac, streamer and HDD for hi rez access. And because I can't leave anything alone, I am thinking of removing the Avr and replacing it with a stand alone dac that will connect my transport and either a raspberry pi or pc to access my flac files on the hdd. Any suggestions? I looked at other threads, but sound quality between the two wasn't addressed.
