I have a bunch from the early days too, almost all of them play, but sadly a few of them (Almost all of them Telarc CDs) have issues on some players now, so I have to copy them on a PC before I can play them in my truck.
My original Magnavox/Phillips player that I bought in '83 is long gone now, but all the ones I've bought since then still work ok. A friend of mine and his brother still have their first players, Sony and Technics vertical front loaders that sound..horrible. I'm glad I didn't listen to their players before I heard CD the first time, or I never would have bought my player when Highland Appliance ( I miss that place) marked them down to less than dealer cost in an attempt to get rid of the tons of them they had at every store. The Magnavox name made them very hard to sell. I think I paid $249, and the list was $899, and the floor price was $499 just before the final price drop. It worked great for seven years or so, then the laser tracking motor got weak, so I retired it, replacing it with a semi hi end Sony "lazy susan" 5 disc changer that was on closeout too.. Still sounds great.
