"Too much potentially, perfect and exact in your comment to be credible to me."
Some errors have exact inverses, so they can be corrected. This is likely to be true for many linear problems associated with electronics, less true for transducers and even less true for acoustics. Examples are RIAA equalization for LP and IEC/CCITT or NAB equalization for magnetic tape. Correction doesn't have to be perfect, in any event, just within perhaps 0.25 dB.
Non-linear distortion is much more difficult, if not impossible, to cancel, because unlike linear errors it results in expanded bandwidth or outright information loss (e.g. clipping). Attempts to cancel this distortion often result in what is perceived as worse distortion due to psycho-acoustic effects.
