Are you sure? In _intro to digital audio_ (p107 fig 4.14), john
watkinson graphs the effects of (random) sample clock jitter on various
wordlengths. He notes that "even small amounts of jitter can degrade a
twenty bit converter to the performance of a good sixteen bit unit.
There is thus no point in upgrading to higher resolution converters if
the clock stability of the system is insufficient to allow their
performance to be realized". 

.1 ns was the pk to pk jitter figure that looked audible between
8-20kHz on the 20 bit noise floor...

Hopefully I'm not misinterpreting, because the math is over my head for
sure :-)
