Hi Paul:

This is an interesting area of investigation too. The audio on just about ALL CDs undergoes 
sample-rate conversions. Most A-D and D-A converter designs involve oversampling, or even 1-bit to 
PCM conversion (for instance, Philips Bitstream, which evolved into DSD; for instance the Panasonic 
MASH playback system).

Just because a hardware or software manufacturer claims something is "transparent," doesn't mean 
it's true in all situations, or to all listeners.
