Encouraging people to consider a traditional 2 channel stereo system.

IEMs, headphones, streaming by phone...if someone even listens at all.

How can we as enthusiasts in this hobby get people interested in a more traditional 2 channel stereo setup using speakers and associated gear? 

Even cheaper ChiFi sounds pretty good compared to what some of us had when we first started but it doesn't take a fortune to build nice sounding systems that work well and can be enjoyed for many years. 

What can we do to support this hobby, its gear manufacturers and promote physical media too although many may prefer streaming?  

Essentially, promoting a gateway into the hobby as well as a pathway for growth and upgrading over the long term?
