[sdiy] uLaw DACs in the modern era?

Tom, do you know that you can easily assess the effect of mu-law or 
a-law companding with only a WAV editor like Goldwave?

Just load up a sound, then save a copy to disc as a WAV file with the 
attributes set to either mu-law or a-law.  Then open this new file and 
you will see (and hear) the effects of the non-linear quantisation.  You 
can do an A/B comparison.  To my ears the quantisation just makes things 
sound slightly fuzzy and indistinct.
