The AES report is highly controversial. Plenty of sources dispute the findings.

Here's a double-blind A/B/X test that indicated no one could hear the difference between 16 and 24 bit. 24-bit is better than 16-bit with dithering so maybe you can extrapolate. AES Journal 2007 September, Volume 55 Number 9: "Audibility of a CD-Standard A/D/A Loop Inserted into High-Resolution Audio Playback" E. Brad Meyer and David R. Moran I found this link with google: http://drewdaniels.com/audible.pdf "The test results show that the CD-quality A/D/A loop was undetectable at normal-to-loud listening levels, by any of the subjects, on any of the playback systems. The noise of the CD-quality loop was audible only at very elevated levels."
