How loud are you typically listening?

What do you mean? IM or THD?

Casual listening - mid 70's

When the family is out - mid 80's

When I want to scare the neighbors - upper 90's

Some systems don't come alive till they are turned up. I find that my other system which has a Class D amp begs to be turned down, in fact it sounds good at all levels. I prefer low to mid volume levels in general.

no access to a DB meter but loud enough to where i can clearly hear the background sounds in a classical recording [musicians breathing, clothes and sheet music rustling, chairs creaking, hall rumble, tape hiss]

I’d like to add that after an exceedingly  loud session I usually don’t listen to my system for a few days.
The danger/fear of developing tinnitus is real enough to keep me in check.

Typically I listen at an average SPL (Radio shack meter) 76-78dB. When my system was at it's best a good example of the range it produced is: Dewy Redmond Choices = quiet passages @ 65db full and detailed, open and satisfying Loud passages @ 86 db and extended peaks at 91 db. now with different tubes, I have to turn it up so the average is 82-83db with less than satisfying musical information at 68db and peaks at 93-95.  I'm aware this is not healthy for my aging ears...... so no steady diet of this.

75-90 depends on the music and the day.

80 to 85 dB is very loud for me if I’m listening to rock/pop. Most other acoustic material is 5 to 10 dB lower than this. Like some of the other posters, I have an old school analog dB meter.

I crank! I'm 65 still listening to Punk and hard rock! My neighbors complain and we have acres between our houses! One night a friend who is a musician couldn't believe how good it sounded! He said I think someone is knocking on the door? I opened the door and my neighbor was telling me my music was 2 loud/I told him I couldn't hear him and shut the door! The cops were the next knock! Ha Ha! My set-u JBL Studio masters I bought new in the 70's/Tigris tube amp and a Primaluna Tube Cd player with a tube clock! God rid of my krell and went back to my old gear! Happy Camper!

ibmjunkman -
71 dB for a burp is amateurish. 
Probably only God knows now what John Belushi could produce!
(Modesty prevents me from making my numbers public).

I weighed in on this discussion in an earlier post - 
"How do I establish a reference level?"

So are most of you measuring C weighted or A weighted. I notice Db-a is the default on the app I am using. When I switch it to C there is a 12-15 difference in the decibels with C being higher. What would be the standard way to measure? If it’s C then damn I’m listening a lot higher than I thought! 

I typically use C scale, which is a flatter measurement. The A scale cuts both low and high frequencies to simulate the human ear's sensitivity at low to moderate levels.  The A reading is only flat from about 500 Hz to 6 KHz. As such, the A scale will appear to register lower than the C scale. Which one is more commonly used depends on the application.

The volume difference really is massive between the 2. A weighted 90 db is freaking LOUD. Measured C rated not so much. 
Is one considered a standard way to measure in a home stereo application? 

Mostly mid 60s, but as much as low 80s if I'm frisky.

@emrofsemanon There free options available at the Apple store such as dB Meter. Might or might not be super precise but close enough.

That’s an open ended question.

How loud do I play what? A Bach violin sonata, or God Save The Queen by the Sex Pistols, or somewhere in between, say Joni Mitchell’s Song for the Seagulls?

I would say that it ranges from 55 to 90, more or less.

And if your system doesn’t sound alive until you crank it up, something is wrong. The best systems - like a lover - whisper into your ear convincingly.
