You want a PC no where in the loop or near your audio system.
@ghdprentice big +1 — a computer should be no part of your audio system. It’s the nosiest source for music, and noise is the arch enemy of good-quality streaming, which is why standalone streamers exist in the first place. Nobody who has a decent system, has any idea what they’re doing, and cares about sound uses a computer as a source. Just go to an audio show — no one uses a computer as a source and all use streamers and/or vinyl. That’s a big clue.
