I did redo the SNR tests on 20 today. The result there with a much better
band noise profile to work with was on the order of 20dB improvement. I ran
most of the tests at 1Khz BW. I'm not trying to overstate the case and
erred on the conservative side judging the meter readings.
So 10-12+ dB improvement in really lousy noise conditions, and 20dB or so in
clearly better conditions.
