So here is my situation, my source is PC with Flac files played using Foobar (wasapi). PC is connected with Marantz 1403 by digital coax directly distance 50ft, speakers are Infinity 163 and subwoofer. The problem is that the sound I'm getting is very mushy, weak and lacks clarity unless I turn all processing way up in the receiver but then again it sounds very processed and artificial. Even the sound from Roku using Spotify thru same receiver seems to have a better soundstage than my PC source. I mostly use the setup for listening to music so it has been a big disappointment. I'm willing to add components(external DAC, media server or amplifier) to get better soundstage other than changing speakers. This step will be using mostly for listening for music so please tailor suggestions accordingly. Any suggestion will be welcome.
Thanks for looking.
