Audiophile demographics?

Excellent. I’m in Washington. Have only driven parts of Mulholland, but drove the roads around Mt Tamalpais where in my 79 SC many curves are so tight and steep you cannot go slow in 2nd. You either go very slow in 1st, or very fast in 2nd. There is no in-between. So I know just what you mean. And congratulations, because that is not something a lot of people can do. Male or female. (I know, from being stuck behind them! 😂😂)

prior to covid i did a weeklong socal drive with some pca/track pals

agree that mulholland is undriveable even in early mornings now, upper topanga still ok - rest of socal good drives are north of santa barbara - greater LA region is just too congested

norcal is better, but also getting harder and harder to enjoy the roads

Have you seen some of the sound rooms, they scream nerd bachelor. Speakers in the middle of the room. Monoblocks on the floor, cables everywhere.
Think about the speakers. Some are attractive and inconspicuous, many are room dominant with crazy colours ( Kanta!), shapes or bases.
Music is meant to be shared.
Hardly suits a solo listening chair laser located.
Function over form.
Does that partly explain the male dominated audiophile world. Maybe we males get sucked into the chase, aspiring to the next level.
Why are we never content?
Some thoughts.

And don't why there aren't more females in the hobby. 

But females generally have better hearing so it seems like something they could appreciate.
