A lot of not mentioned things are the type of music one likes (though a few if the recent posts DO mention what type of music being discussed in the dB comment) It is easy to have realistic volume listening to a solo artist playing an acoustic guitar. Same for piano, or even Classical chamber music at relatively low SPL
But them you have Death Metal. That expected dB is 100? Also the amount of bass. Particularly low bass, gut massage bass.. adds a LOT to the dB meter. So folks WITH a sub, or strong bass output speakers will have a higher dB than folks playing the SAME MUSIC without a sub or prodigious bass output
In large Classical, and in Opera, only the climaxes are really loud..
(thus my personal 80dB for opera climaxes)
So some of the disparity of folks playing levels is ’what they play’.
I seldom play Heavy Metal! And little Hard Rock.
The vast majority of what I play is small combo Jazz, Small scale Classical.
One other point is nothing is lost playing at lower levels with good equipment. (though when I hit the bottom, like extremely hushed passages in an orchestral piece and the music is too soft to actually hear well, yet the loudest are louder than I want to play at,, Talk about dynamic range.. But that is rare.. My latest cable upgrade made this more of a problem, though like I said, only rarely and particularly on large scale Classical.)
