Thank you Cliff for the comparison, much appreciated. Maybe I had a rough day yesterday... But I will try to down grade to 12.09, then record and compare with 12.10Auditory memory for frequency response is very poor. Many times we think we hear something that wasn't there before but we're mistaken.
FWIW here is a frequency response plot of 12.09 vs. 12.10 with a low E and high G input to your preset.

The plots are identical (measurement noise not withstanding).
