Pubul57, I know what you mean; however, we should clarify for semantic purposes.
I think we'd agree that a superior rig/speakers should allow the perception of the most natural/accurate/non-editorialized playback of the recording, whether good or poor.
I believe that superior systems/speakers will always make poor recordings sound better than on average systems. The better the system/speakers, the better the recording will sound. Now, perhaps we may not like the improved sound, due to being used to hearing it played back more poorly! We can have nostalgia, preconcieved notions about how it should sound, etc. That can color our perspective about the higher end playback. There have been many times I have had to adjust my expectations as I have heard an older/poorer recording played back far better, but it has sounded so dramatically different than I expected. That it was being played back at a higher fidelity level was incontrovertible; I had to get used to the fact that the music was different than I had imagined. One hears more of the flaws, but also more of the nature of the instruments, voices, venue, etc. If that is not the case, then I suggest there is a serious problem with the establishment of the rig. A poor recording is a poor recording, but an outstanding rig will make all music sound better, including poor recordings. A superior system is the tide which lifts all boats (recordings).
In that sense, then, I seek a speaker system/speaker which allows poor recordings to sound holisitically better. So, I think perhaps we are in agreement.
Disagreement over speakers is partly a function of the editorializing we all conduct when we establish our rigs, setting them up to suit our preferences.
