Does loudness play a part in your appreciation?

Probably because of scar tissue on both eardrums, but even with hearing aids I need peaks at 85db to absorb all I'm capable of hearing. That's an improvement just in the past year, attributable to to an amp upgrade, 85 has now become the new 95.

Under 65 db my system doesn't really come alive, due perhaps, to the size of my space. Over 75 db is too loud for me. 70 is about right.

For me, the perception that the volume could be recreating near the original volume makes listening real. I realistically also listen to most music at that 70 to 75 db range, but I have pulled the meter out to occasionally find myself in the low to mid 80s. So it depends on the music.

For the most part,I enjoy the music I'm listening to regardless of volume level.HOWEVER,there are many times when a song triggers associated memories..Most all the time,those songs are of the variety that are high energy & I'll turn that volume knob clockwise which does seem to add to the enjoyment factor...

It's a great question actually. I've wondered about this myself some lately.  

A friend and I were comparing listening sessions recently and I realized we like to listen at different volume levels. And, thoughts around how each of our systems will sound different if he's listening at 80db and I'm listening at 70db most of the time.  

My system's character changes overall when comparing 65,70,75,80-85db listening levels. I don't care for how my current system sounds when the volume level is turned up really loud. My level of interest and engagement drops notably.
