No, because those non-linear effects shouldn't be there in
the first place. If you reproduce the wider bandwidth recording
over 'perfect' speakers, the intermodulation products will not
be there and the original signals above 20 kHz will not be heard.
The result should be the same as a recording limited to 20 khz.
It makes IMHO no sense to require a wider bandwidth just to
exploit a deficiency of the reproduction system. If the 
distorted version sounds better, the distortion should just
be added in the mix.

-name should do it. I'm not 100% sure it's in the current
release but I think it is (the version I use here has evolved
a lot - new release expected before LAC2006).
