@kjl1065 an acquaintance of mine has O/93‘s. I asked him to do a test at 50 DB and report back. For reference this is a fellow who normally listen to more at 90+. Here was his report.
Larry, I tried listening at near whisper quiet volume levels for a while this morning & I can confirm that it really depends on the recording (how much bass; how much treble) as to whether the DeVores sound "full range" at around 50dB or not...Bon Jovi sounded anaemic (but it kinda does anyway) & Virna Sanzone & Steely Dan - ’Two Against Nature’ sounded quite full range enough to me, just a little too quiet. Maybe It would be more ’full range’ to some listeners late at night when 50dB is required 🤔
For me, I have no sonic deficiency complaints at around 50dB from my O/93s...and now back to normal listening levels...phew! 🙄😂
