sibilance and harshness I was getting in the sound...


Please note I'm referring to one of the internal regulator chips, not
the AC supply. It's not a significant change unless you're counting
picoseconds of clock jitter, in which case it is a tiny improvement -
see the audiophile forum for more about jitter.


How about RF EMI?  Was that internal switcher generating/broadcasting
anything significant?
