however, if you check the level actually put out by, say, any cd player
it's quite a bit louder than -10dB

That's why, for instance, my M-Audio Sound Interface has 3 input/output 
level
settings
-10dB,  Consumer, +4dB
..with consumer being the kind of level that usually goes down phonos.


The -10dB really was a standard (nominal level) when we had those 
5 pin dins....remember them?  I do.
..and then phonos were introduced...and they really did carry a 
higher level.


I even had a with both 5 pin din (-10dB) sockets and the newer
phono inputs, and the phonos were less sensitive.


So I can guarantee you that I'm not bullshitting you...
...I actually *measure* this stuff.

Maybe there's a kind of volume wars going on for cd players,
trying to sound impressive, but the concept of "nominal" has
at least been stretched by consumer gear.

"Volume Out" on the EDP does exactly that.
