I mainly go by my local audiophile group and we have several female attendees, when we do equipment comparisons that number goes up because we use musicians, audio engineers, and many with science backgrounds.
Audiogal gave a very accurate assessment of tubes I sent her with a loaner amp. There are many males who cannot do that.
There is such a thing as the accuracy of large groups, take fifty people, average the results and the result tends to be pretty accurate. The young woman in question picked the finish of 20 different DACS blind with the same accuracy as a group of fifty. Now mind you she does not know wire types, OCC, silver plated, whatever but she can consistently pick the same types from a large group, once again blind listening. I have had plenty of people "say" they can hear this or that, until given the same test.
I also had someone here state cooking his AC cables going to an amp made a world of difference. I had the same cable cooker in my possession at the time so I offered to cook four cables, and leave four as they came out of the package. All he had to do was tell me which were cooked, since there was such a huge difference. He did not wish to partake in that experiment for a whole bunch of reasons lol. Whenever someone makes a claim I tend to say "great, show me!!!."
