My daughter is in ninth grade and I've been taking her with me to a great indie record store ever since she started showing a serious interest in music when she was about ten. She's into punk mostly and much of what she likes is nearly impossible to find anywhere else around here, although I only buy her CDs. She does have CD-R copies of quite a few of my LPs, though. Anyway, none of her friends' parents even have a turntable, nevermind her peers. And while she agrees LPs usually do sound better she doesn't care. Hell, I often find her listening to mp3s of CDs I own.

I guess I've always cared about sound quality because when I was a kid I only ever had junk stereo systems/boom boxes to listen on. My parents had a nice Pioneer receiver/AR speakers/Realistic turntable so I did know what I was missing and would use their stereo whenever I could get away with it. My daughter OTOH grew up with a Marantz receiver/Mission speakers in her bedroom so she never had to suffer the truly awful sound quality I had to put up with. She does say that most of her friends' stereos sound like crap so I guess she does care about the difference somewhat, but even her friends' Sony mini systems, etc. are light years better than what I had at their age.
