if one configures a stereo system to minimize errors of inaccuracy, it may be possible to alter the sound of a stereo stereo system to accomodate inferior recordings.
for the majority of one's recordings one would maintain the "virtually" neutral system. for the few "bad" recordings, one could apply the bandaids, and then remove them .
thus one creates the best of both situations, the better quality recordings and the poor recordings, without incurring the wrath of shadorne and the other perfectionists on this forum.
