I'm curious. What is your "normal" listening volume?

For me depends on the dynamic range and compression level of of what I'm listening to.

- Classical with many peaks...peaks over 90, average 50 - 60.

- Wall of sound rock / metal (Devin Townsend)...60 max.

- Small acoustic setting...60 - 70.

More during the day, less in the evening. 8 - 9 ft away from ML Ethos.

85 db usually for active listening. It’s enough to achieve a full soundstage and I admit my Magnepan .7s aren’t at their best at low volumes.

Great question. I measure this from my listening position. In a normal size room (12x15) I listen at 75dB. I used to listen at 10dB louder but that was a single-family home; now I'm in an apartment.

75-85dB in large open great room. 

Typically less than 90 dB and always less than 85 when the dogs are with me.

My understanding is that this will not lead to hearing damage if exposed for only a few hours a day.

I do not think my system needs more work. It's all personal preference and the music to which one listens. Eva Cassidy at 90 is not my cup of tea but nor is Captain Beyond at 70.
