Agreed, there's no sign of a midrange depression in the Stereophile measurements. But the electrical dip is only 3.5dB at 600Hz, possibly too small to detect on the Stereophile graph. Also the graph doesn't correlate with the boost in the lower treble noted by the reviewer.I found the shelving quite interesting because I too observed shelving above 2KHz in my crude measurements, but this was the frequency at which the comb-filter effects ceased, i.e. the peaks and nulls faded into a continuum. If I consider only the peaks below 2KHz, I get a graph that's shelved like Stereophile's. If I average the peaks and nulls below 2KHz to a level half that of the peaks, the value was approximately the same as the value above 2KHz. I had dismissed the shelving as a measurement artifact (but I had a *very* crude setup).
After listening to my electrically-flat crossover for 3 months, I'm convinced it has a midrange emphasis. I'll probably continue to adjust it, and try the stock crossover once again.
