As system improves, do bad recordings sound worse?

My early efforts to improve my system usually resulted in making bad recordings sound worse. But at some point in my upgrade history, bad recordings started to sound better - in fact, better than I ever thought possible.

Anybody have a similar experience? Anybody have a theory as to why?
hi byron:

the issue is what is meant by "improves" and what is considered a "good" system.

i believe that audio is a subjective hobby so what constitutes "improvement" is a matter of personal taste.

if improvement=greater resolution , while maintaining a balanced frequency response, i maintain that recordings which are engineered to have a peak in say the range, 1000 -3000 hz, will sound more fatiguing.

i did raise this question as almarg has indicated but i was a bit vague about what constitutes a poor recording.

i am trying to be more specific by saying recordings having frequency response errors will, in a better system, as i have implied be exposed to a greater extent than in another system with certain colorations.

In my experience, most definitely yes.

Depends on what you compare to.

They may be more disappointing and seemingly worse in comparison to good recordings now but should still sound better than they did originally.
As system quality improves, it becomes increasingly difficult to make lesser quality recordings sound agreeable. However, since this is all about MUSIC, the essence and spirit of the performance can be brought out regardless. Any system must have a SOLID foundation of the three pillars of audio: 1)power 2)acoustics 3)resonance control. Per a phone conversation on this particular subject with Albert Porter a few years ago, he told me that his system could successfully play any recording, but that any change could take him up to a month of tweaking to get it back on this track.
