I decided to do some more detailed investigations,
because while I
totally accept your statements, the actual measured results were quite
different. I was getting an essentially flat response right the way up
to 99.9kHz, a little wobble between ranges but no more that +2dB, and
about +1dB at 40kHz.
Compared to the 0.1% spec on the resistors these are
big errors. 1dB is 12%. 0.1% is less than 0.01dB.
A reasonable target would be 1% accuracy, that is less
that 0.1dB.
