Audiophile demographics?

I know two people both (still) into hi-fi (one very much so) who became transgender and now both have changed sex  

Like vets (animal doctors not retired soldiers) women are more prevalent than their male counterparts in lots of things- musicians being one example and not just flautists and bands of old such as The Breeders, Girlshcool, Siouxie and the Banshees, Susie Quattro, Alice Coltrane, Barbara Dennerlein and Barbara Thompson etc..- also compare modern orchestras to the 50’s.

Strangely not yet in the weird world of hi-fi ( though my mum still has fond memories of my folk’s first place where there was no furniture apart from a bed but there was Quad and Kefs- ESLs were too expensive even then).
