I found this article linked from the Devil DAC site.  It's the story of the development of the PCM2702, which is one of a family of chips used in a large number of USB audio devices.  It discusses some of the problems and solutions in USB audio (and digital audio in general) in a way that's fairly accessible to those only moderately technical. 

Here's a link to the printable version (much easier to read than the regular format IMO): http://www.planetanalog.com/article/printableArticle.jhtml?articleID=12801995&printable=true

Thanks Brad. I've exported them to PDF to read when time allows.
