High end stereo? Mario, actually mine still works fine, in the same two rooms I set it up in 1976.
I'm not enough of an audiophile to even know if I have a high end system but I have a 100W Sony reviever driving 2 Pioneer towers and a 12" powered subwoofer all connected to my Smart TV and CD/DVD player. We mainly listen to Pandora on this system.
Our 2nd system involves an Onkyo 5.1 reciever driving 2 large Klipsch speakers also connected to a CD player and my PC. I have several playlists of favorite artists on Windows Media Player that I can jam along with on my bass.
Both systems deliver superb audio to my ears.
I know vinyl is coming back/has come back but personally I don't see the point. My last turntable died decades ago.
