Well retro is big right now so maybe somehow these new younger folks will want to explore some of the great stuff from the past. Which can easily be used in the present.
Look at all the young guys who want 60's, 70's or 80's retro cars or trucks. Vintage is big currently.
We need more places playing speakers of the past to show what can be found from the past.
I'm still very AMAZED by all the really high end companies making stuff for home audio. How do they all survive selling amps and speakers for those kinds of monies?
