Core Audio Internal Compression?

Go to your audio settings in Audio/Midi setup.  Notice you can switch between 24-bit and 32-bit audio output formats?  In the former case, there is a noticable compression going on to avoid digital clipping and distortion.  In the 32-bit case, not so much.

Its definitely there.
