The only thing you should do with your digital equipment is not to shut it down.

I would say since about 2005 or so, dynamic range >16-bits has been routinely achieved and with the asynchronous USB DACs these days, jitter has really become much less of an issue. I suspect the days of companies blaming jitter as what's causing bad sound needs to come to an end.
