I was at the AES meeting where the first hi-res digital recordings (20- 
and 24-bit) were demoed, and members of the panel talking about them 
noted with some surprise that the new recordings all seemed to have 
better bass than the 16-bit ones, and they couldn't figure out why.

Try this: take a good 24-biit recording and dither it down to 16 bits. 
Does it lose something in the low frequencies? In that experiment, 
you'll be using the same hardware on both the 24- and 16-bit versions, 
same power supplies and all. Try it; I'd be interested to know what you 
hear.

Peace,
Paul
