Why do almost all women today hate home audio?

No one should actually listen to music on a phone speaker.  
I’m not even saying that as a musician and audio nerd.  
As a human. Living in society.  
Don’t do it to yourself, and, for the love of all things holy, DO NOT subject innocent bystanders to the inarticulate, shrill noise pollution that constitutes “music” being played through a phone speaker. 

don’t care very much about home audio. This is a very tiny niche market.

when I grew up, everybody (boys) wanted a system. It was called hifi-tower. An amp, receiver, turntable and 2 giant speakers.

In the late 90s, everybody (men) wanted a Bose wave radio + CD player. (I thought it sounded horrible, but that's besides the point)

I don’t know why it would be a tiny market today. Based on Amazon’s lo-fi products’ reviews, there are millions of people buying speakers that are infinitely better than the iPhone’s speaker

I don’t know who does and doesn’t listen to hi-fi, but I do know that every realtor I have ever spoken with has said if you want to sell your house, the hi-fi has to go, including the two I had to crowbar out of the sweet spot on occasion. No one wants to even see it. An empty room would be better than a dedicated one. The most clever one asked for a ballpark value for my rig, because that’s how much he was going to reduce the asking price. Then he offered to buy it. I set it up at a friend’s and our house sold for asking a couple days later. 
 

My two 4 year-old granddaughters love to dance in the room with the “big music”. My wife made it half-way through Songbird asking how I could stand to listen to something that intensely intimate. Same thing with daughter-in-law and Just a Little Lovin’. She barely made it to the bridge before it was, “Nope, nope, nope way too emotional.”

Wow my wife just wants to make love all day, maybe 3 - 4 times a day and not even while listening to music! What’s a guy to do who just wants to be absorbed by music?

The young demographics' excitement with music reproduction is with headphones. Cheaper, easier to get into, and can exceed 2-channel in many ways.
