Women need to be doing at least 3 things at once, so to get them to focus on just music for more than 20 minutes without cleaning something or straightening something up is almost impossible. A lot of women like music only as "background noise". They keep it low while they're doing something else, and don't really pay attention.
Beyond that, they are practical and very "thrifty". I think many of them wouldn't mind if a man bought them an expensive system; but they wouldn't buy one for themselves.
Plus, they generally lack physical strength (for moving things around) and the electro-mechanical sense (for hooking components together). Also, they hate all the clutter of the wires, etc. What men see as "cool", women tend to see as "unsightly".
Add to this that the quality of the reproduction is not an attraction to most of them (sad). The difference in sound quality, unless grossly obvious, is not something the average woman would notice or care about. Whenever I insert a new piece of gear in the system I sometimes ask my wife what she thinks. Her answer is almost invariably, "It sounds about the same to me".
I realize my comments may be upsetting to some, and that there will always be a few exceptions, but by and large, that's the way it seems to me.
