As long as our ears remain "analog" we will need good speakers and amps to move air around (and the cables to connect them).
This audio thing is a moving target. Those manfacturers who put their fingers on the pulse and fully resonant with the end user will be okay. Unless, of course, they do something incredible stupid. Which could happen.
Going to be interesting to see what happens. Hope the legacy brands stick around for a couple of more decades, or until to break my neck on my 90th birthday -- pole vaulting. Which ever comes first.
