Re track 25 "Bonger Test" on Chesky JD37 audiophile test disc, recorded by Bob Katz:

When played, even at low volume, I can hear distortion (clipping) in the -3 and -13dB tones. When I extract the audio file to my hard drive and examine with an editor, I can clearly SEE the clipping. (FYI, there is no clipping on track 26, the Bonger Test created with "standard A to D.")

Why am I seeing clipping? Is the data on the CD actually clipped, or is my CDROM drive to blame for extracting the audio data poorly?
