Perhaps it is worth fixing if you enjoyed the sound? I had Cambridge Audio player that over years lost most of the felt on the ring that squeezes CD down. Something like that should be easy to fix. Recently my MacMini stopped reading CDs. Using "cleaning CD" didn't help, so I opened it and cleaned lens with Qtip and Isopropyl alcohol - it works fine now. Putting a little of oil on the gears might also help. I assume that it is (as usually is) mechanical failure and electronics is OK.
