I have nothing solid to say about the dither test.
I just joined the thread to be in good company +s all around.
FWIW, the differences in the dither seem to affect the least heard parts of the music.
Although it ceratinly isn't a moot point, as we want to hear as best and as much as possible,
it isn't nearly as important as location, mic selection, gain structure, pres, and beer temperature
I've heard a few pros say that they like POW-R best of all.
I'm not sure what they heard to justify that.
