However, Darkkeys not to worry:
Case in point: I listened to an old DECCA recording from 1963 of basso arias with Nicolai Ghiaurov just now, a LP, which got several distinctions and which is in perfect synergy with the analog part of my system. I then listened to the reel to reel tape (Columbia M2Q 516, 1963) of Mahler's 9th with Bruno Walter, a recording which is anything but perfect and also the tape machine is not quite up to the standard of the rest of my rig. Actually I should have listened the other way around. The mediocre first and the "perfect" afterwards. The point is however, Bruno Walter's conducting of the symphony was so outstanding, that after a few bars into the music, you completely forget what was alluded to above:
"if a stereo system is minimally inaccurate, there will be instances in which it does not sound pleasant, as a consequence of the quality of the recording".
If you like the music as is, you get drawn into it, forget about the system and the rest is just talk and that goes for any kind of music, not just for the classics as in my example. Condition for this to happen is of course that you are a music lover, just as much as you are an audiophile. But even if you are just an audiophile, fixated on how your rig sounds, you will find that your ears will adapt to the changes in rendering more often than not, which can make things difficult to judge properly, as we all know.
