In an optimal room/system acoustics, everything sound better because it is better perceived...I listen great musician badly recorded too ...
I am interested by the acoustic translation from the recording , good or bad... If i love some music , the sound bad sound recording does not matter anymore especially in a good system ...
it is more difficult to appreciate good music badly recorded in a bad ausio room/system than on a top audio room/system ...
Now what i said is meaningful for classical... In pop/ rock bad recordings are more than often simply put aside because of the poorness of the musical content and /or the easy availability of alternatives pop/rock albums more well recorded with a better musical content ...
In classical, nothing will replace Sofronitsky interpretation of Scriabin or of Swzeryngk Bach less well recorded than other versions ... And sometimes even a very bad recording will be valuable because of a unique interpretation and a deep musical content ...
I need a good audio system especially to be able to hear better bad recordingsb with deep musical content ...I listen music not my system ...
