Repair or Replace ???

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.

Vinyl players are more reliable.
Have 4x Technics 1200(DJ use)
1 Empire 698 since 80's and Michell Gyro SE since 2001.
All of them woik like nu.

Meanwhile changed CD-players many times for various reasons and quitting reading or jumping isn't out of that list. After Q-tip wiping and blowing the dust out of mechanizm it worked for a while but than again same story after a few months.

Clean it wipe it, make sure it works than sell it as-is with disclosure. That was my game. Another reason formats are always changing and you want to use the best with corresponding player capable to play specific format.

Out of my record/book/cd/media store shelves with CDs are slowly being depleted as more and more space is needed for vinyl due to the demand.

Czarivey, you might be right - my brother has vertical Technics turntable that works flawlessly for about 40 years.

Kijanki,
Your brother is very lucky. I get them to my store from customers with tough problems such as blown photo-diode which is basically a sensor to position tonearm. That part now is irreplaceable in vast majority of vertical TT. Once it happens the only cure is to replace the tonearm system and lay it horizontally.
