I am listening to the same volume as before (2db less, actually). When my neighbors are not there, volume calibrated such that fortissimo is between 98-102db (depends on recording), pianissimo is a little under 60db, and piano-forte/forte ("regular" volume) is around 85db.
I do not live in a church, so my needs for high-SPL is not that big.
But gotta have the accuracy!
I did listen to some solo violin and then a minute or two of a string quartet at +10db (both SACDs), which was probably frequently hitting (sustain) 106db. String attacks are usually way higher than that, but they are hard to measure with cheap SPL meters meant for calibration.
