If I listen to all three discs of Bach’s Cello Concertos I certainly do not change the volume. But if I then listen to a symphony that is recorded from a further listening perspective and if the record sounds quieter or louder, I adjust the volume.
as I thought I expressed clearly in my post, different music in different recordings depending on the number of factors sound best at different volumes.
I don’t want a close mic’d recording of a piano in a chamber setting to sound the same as a piano up on the Boston symphony stage as heard from row M. The listening perspectives are different and that should be reflected in the experience at the listening seat in my living room.
Gene Simmons belting it out at a concert is a different volume then a soprano heard from the directors box at the Vienna State opera. I may have heard these thirty years apart, but I think it’s safe to say the volume was markedly different. And if I want to try to approach some semblance of re-creation from recordings in my listening room, the volume setting will be different.
