As long as you take a passive approach to music reproduction through your system, then yes. You are stuck with the sound quality baked into the source. My approach to music listening is more reactive, so I do what I can to compensate for poor productions of great performances by expanding the dynamic range of overly compressed material, adding room tone back into overly dry recordings, restoring the bottom octave of commercial releases that have had it whacked out to "fit" the medium, etc.
No, all this manipulation doesn't make a crummy recording sound as great as a truly well-produced release, but it does improve my enjoyment of it, and that's my goal. Before I start catching a ration of shite about altering the musician's intent, let me remind everyone that most release approvals are phoned in, so the musicians rarely have any idea of how the end product actually sounds.
