Does Age Matter?

No it does not, my simple answer as not all aged ones have an RTR deck or cassette. On the other hand it is more difficult and costlier for a young one to built a respectable vinyl collection. Digital is easier to operate, sounds good, and is very easy to obtain. You can teach an old dog new tricks for the ones who sold their lp collection when digital appeared and for the ones who seek a more complete approach to sound reproduction. 30 years ago i would not care for digital but today i want both.

39 and digital. Music discovery is extremely important and digital provides this, as well as accessibility that I would have never thought possible while working at Tower Records 20 years ago as a poor college student. Vinyl, at least right now, would be too costly.

Collecting records from approx 25 years (just after university)
From 30 tried to capture digital for 10 years, do own DAC which is off for the last 3 years. 

This year I bought LPs for my 37 year old nephew and the 16 year old daughter of my best friend’s son. Both are starting vinyl systems for the first time. So as far as my personal anecdotal experience goes, no. Your generalization does not apply.

I honestly don’t care about the format. Over the years I have learned to appreciate good music and how it sounds regardless of the recorded medium. I equally enjoy spinning Vinyl, CD’s and Streaming tunes. There is no clear winner in my system and to my ears simply because of the attention to detail towards each competing format.

As @chakster pointed out, Streaming is a great medium to discover and appreciate music. What’s remarkable to me is how Vinyl has managed to sustain its presence in last 50 plus years :-)
