This is probably a misunderstanding: I said that the material 
that suffers is usually quiet, not that all quiet material suffers.

So do I, and I included a few unaltered samples with plenty of 
headroom in my standard test corpus for these improvements.

That is certainly not the case. The compression level retuning 
doesn't work beneficial for all material, but it is in this case 
simply coincidence that it is some quiet material that seems to 
suffer. The patch attached to this thread you're replying to 
however, for some reason benefits specifically this kind of sounds.
