What do you mean by poor production? The original recording, which is part of the sound of a band for example, or the transfer of the master with any additional DSP (loudness, noise reductions etc).
I only ask because I don't get the concept of a good system making anything sound harsh, as if it is so truthfully revealing as to be a positive characteristic. I had some recordings that used to sound a bit rough, but on my current system just have a different balance. In that respect I have re-discovered some albums.
