We found in studies that there are a variety of anomalies at the beginning 
of the sample which don't show up on the source but are apparent on the 
destination.

Most software samplers, including the EXS, are much faster responders than 
their hardware counterparts. They work "computer perfect" so to say. For 
example, if a sound has lot's of low frequency content and does not start 
out at 0 amplitude, the EXS will sometimes "complain" that is, put a 
audible pop in (which makes your Bass library report not surprise me). Same 
with other software samplers - Giga, HALion, etc. There are other things 
that cause this as well.

For this reason, in Translator, we put in a "fade-in for computer based 
samplers" option, which fades in the first 16 samples; forcing the sample 
to start at zero amplitude. We were going to just go ahead and make this 
automatic, but we found that the "glitch" is actually preferable on 
percussive type sounds (drums, etc.). So it wound up being an option that 
you can use whenever something like this happens.

Check your .wav's on your example - do they start at zero amplitude, or do 
they start at 3000 - 5000 whatever? Is the glitch more pronounced on the 
lower frequency samples?
