Let us suppose the following:
1. I have a SB16 (false, but assumed for the purposes of argument)
2. Instead of Seinheiser's, I use a pair of Grado SR60's (true)
3. The Grado headphones require more power than the Seinheiser's to
produce an equivalent sound pressure level. (may very well be true; many
of the Grado headphones are reccomended for use with external amplifier's)
4. I aquire a binary copy of your driver-- (false, but binary drivers are
installed with many distributions-- such as redhat)
It then follows that the sound coming out of my headphones at maximum
level is too soft for my enjoyment.
Now, let assume that I use earbuds which produce a higher Sound Pressure
Level than do your Seinheiser's. The artificial maximum will blow my
eardrums out, when I listen to the 1712 overture. Oops...
