It is always possible that the data on the CD really is clipped. You 
might try reripping with cddatowav (from cdrecord) and see if the data 
looks the same. That software uses a modified paranoia library.

Your equipment may be compensating in some way for the problem, the 
chances of three readers being bad in the same way are very low.

My thoughts are not only delayed, but fairly obvious. Occam's Razor 
here, if three readers agree the data are clipped, suspect the odd man 
out, in this case your normal playback hardware.

I assume you burned a CD of the clipped data and played it on your 
normal playback hardware to see if the clipping was obvious there.
