I was going to give my son a system, with brand new Solid Steel rack but he has AirPods???


AirPods and iPhones have replaced good 2 channel audio, it's criminal. They don't buy albums, CDs, or even the full album downloads. They've replaced my old 45s with mp3s.
I got him a Solid Steel rack and I can't return it, so what do I do? Sell it on eBay for local pickup or wait for him to get smart. You would think a mechanical engineer wants a Scoutmaster and a beautiful really well designed audio rack. I get he doesn't necessarily want my old Rotel amp and preamp, but I have a set of B&W CM2s on stands and he could get himself a home theater integrated amp and use the system to watch Movies at the least.
Where have we gone wrong?

I have two sons.  One lives in CA the other about 10 minutes from my house here in MD.  I have a ton of vintage gear that I've been giving away to family and god children, and had planned to buy each of my sons a decent 2-channel system. 

My CA son wanted money instead, which is fine.  I sent him a check.

My MD son wanted some of my vintage gear because that's what he grew up with, and he's really into music (as I am).  I gave him a Pioneer SPEC-4 power amp, Rodec mixer, Soundcraftsman EQ/Pre, Technics SL-1600 MK2 TT, McIntosh CD player, McIntosh Tuner, and DCM TimeWindow 3 speakers.  I offered him a complete McIntosh stack but he didn't want the McIntosh MC-2600 power amp or McIntosh 31v preamp/controller.  I'm OK with it because I'm just trying to downsize.

Here's the deal you've a hobby, a sound system, maybe extra equipment. Your kid's probably grew up in your house and likely were exposed to hearing and all involved. The key word is they grew up, and developed their own way of thinking wants and needs, bingo you've done your job.
We can't expect the dumping of unwanted or unvalued junk on them to be accepted. Attempt the turn over if excepted fine if not there's always ebay...
Move on.
My daughter just started graduate school, and moved in with the Boyfriend.  I gave them a McIntosh RS100 for their new apartment.  They love it.  Can't wait to show up and hear it.  Obviously better than an Amazon Echo!  Plus, now they are a proud part of the McIntosh family without having to drop thousands of bucks!  It is a parents role to properly indoctrinate your children!
My son is in his early 40’s. He grew up listening to music on my various systems, mostly vinyl and CD. He was always interested in music as a kid and has been to many concerts. He was also in a band for a few years until marriage and kids took priority.

About 8 years ago, without any encouragement from me, he started buying used LP’s and playing them on a Crosley type record player.

A couple of years ago, I started upgrading my system and gave him a Rega P3-24, Harbeth C7es3’s and a Yamaha integrated. He is absolutely thrilled with the sound quality. Now, he even buys the occasional new LP.

Just recently, for his birthday, I gifted him a Node2i and a subscription to Qobuz.
It gives me immense pleasure to see him enjoy good quality audio.
