What does Hi-Fi Even Mean anymore?

Addresses in no way?  
I’d argue it addresses 80-90%.  Maybe more.  

Good luck finding unamplified music.
Even the buskers have battery smpsy.

Hey.  I just like switching on the steereo, sitting in my easy chair, and listening to a few tunes.  In the best audio fidelity I can reasonably muster.

It's means what it's always meant. The McIntosh guy got it about right. 

 only those of them who attend a lot of live unamplified music have kept touch with the original aims of hi-fi.

Good golly gosh. So I can't be hi-fi, because I haven't attended a live acoustic music event in years?

Holy elitist, Batman! Where do they get these ideas?

Yes Robin, but the arrogance of some people knows no bounds.
