Does Age Matter?

59 - 100% analogue on the stereo, CDs in garage while washing car, CD or Sirius/XM depending on which car I am driving.

Statistically this is a waste of time since you are setting the Mendoza line arbitrarily at 60 (although I like thinking I'm in the younger group of something) and not breaking the age groups further as CDs had a relatively short life span. If you're talking streaming, that will be around, but is relatively new. Vinyl was first and is forever...

77 and I just traded my 350+ CDs for vinyl. I have nearly 600 DATs but the players won't work. I've been listening to vinyl for 75 years, I never gave up my vinyl rig even at the height of the CD/DAT craze. I never had R2R but I coveted them.

tuberculin, a man of my own heart. That is exactly what I did. I burned all the CDs to a hard drive and traded them in for vinyl, about 3 thousand of them. What fun.
Hobbitinablender, I can understand how you got that username. My response is, who cares. There is plenty in this thread to chew on. These are all people who love to listen to music. So, it really matters to them in comparison to the general population. I chose 60 for a reason. I probably should have split the group at 50, but here we are. Everyone over 60 grew up with vinyl. By the time the younger group turned 20 digital started to take over. Their experience with vinyl would have been much more limited. 
Older people seem to prefer digital because it is more convenient. Many of us run both but very few older people do Vinyl only. The vinyl only population is the younger guys! The group with unquestionably the better hearing as we all decline with age. My hypothesis was 180 degrees backwards. Live and learn. 

I'm 71.  Bought my first CD player in 1984.  Haven't used a turntable in 30+ years.  All of my vinyl is stored in boxes.  Could care less about LP's.  Way too much work to keep them clean, setup the turntable, etc., etc.   At this point I use a Bluesound system and haven't even turned on the CD player for 2+ years.  I guess I fit right into your theories about age...eh?

I am 73. I have a large record (LP's) stock. 
Yesterday my grandson and his friend stopped in, both seventeen, his friend clearly impressed, looked at the covers front and back, said he loved records and quizzed me about getting good entry level turntable etc. There are a lot of young ones that prefer vinyl.
Before the Covid thing I would see many 12-16 year olds at record fairs amongst us oldtimers. I would step back and let them search first.
