I'm reconfiguring the 2-channel system in my office. I'll be using my PC as a jukebox for .wav and .mp3 playback, and outputting the signal to a receiver or integrated amp, depending on the information I learn here. This is the question. When playing .wav files on a PC in this type of set-up, is it preferable to make a digital connection between the soundcard and a digital input on a receiver, or should you use an analog output from the card and connect to an analog input on a receiver or integrated amp. I understand the difference in the case of deciding whether or not to connect a CD player digitally: it depends upon whether you prefer the DACs in the CD player or the receiver. But what about this situation? Is the digital-to-analog conversion happening in software, or in the soundcard, or am I totally confused? Thanks, in advance.
