The mid-fi market is alive and well. The sound quality has moved up a good bit. Audiophiles are everywhere, (they just don't know they are audiophiles.) They are using IEM's and they sound really, REALLY good!! Yes, even with Spotify or You-tube.
The more affluent group are using sound bars with subwoofers usually connected to the TV. Both in the den or out on the patio. Honestly, they sound pretty darn good and are perfectly adequate for dinner parties or half time shows during superbowl.
In car stereo is better than ever, especially when connected to stream off the phone. Big sound improvements have been made.
Everyone I know has one or the other. Music listening is everywhere. Even on the golf range hitting balls!!
