Really not an issue.  We're not comparing tungsten (et al) diffusion light
sources with condensors, we're comparing cold lights with condensors, a very
different matter.  Acutance IS certainly affected and is at issue with these
smaller negatives when enlarged to many diameters with either type of
diffusion.  Cold lights add another problem that tungsten diffusion sources
don't - printing with VC filters is VERY difficult since with most papers,
the light source alone starts you out at between a 3 or 4 equivalent grade.
