What decibel level do you listen at? What is ideal?

For jamming rock mid 80s to mid 90 peaks ,

easy listening in the mid 70s , late night maybe high 60s 

Between 80 and 90 dB C-weighted on Decibel X iPhone app. Can't feel the bass much below that.

This app monitors the session and gives an estimate of how long before ear damage occurs. Keeping it below 90 dB pretty much allows you to listen for hours.

80db+ is typical for me at my listening position which is 12ft from my stacked large Advents.

Flashback to my college days. Great speaker(s).

45 years ago, when I spent a lot of time in movie theaters, our Dolby techs would put a microphone half way back in the seats just to right of center and set center channel at 85dB, left & right at 83dB and the surrounds at 81dB (using pink noise).
