I listen to almost everything on low or very low volumes.
(Except occasional blasts of rock music, often when people are out.)
I do this partly to save my hearing, and partly so as not to disturb sleeping children above the listening room.
There is usually a ‘just right’ volume range for that track at that time.
I try to stay at the lower end of that range most of the time.
As far as I know, one aspect of Eicher’s approach is to start tracks softly, to ease the listener into the music.
