This is just measuring for the sake of measuring. And that goes for all these cd players articles lately.
Rip your CDs to a hard-drive, recycle CD player after that. Done.
No measuring needed.
Well there might be 2-3 readers here who are in love with that "I'll go up now->browse my CD collection->press eject button on my CD player->put in another CD disk->grab a seat->repeat" cycle but they are most likely to eventually get the medication they need.
Some of us appreciate the reviews and the work invested by @NTTY into these. I love vintage gear and have plenty of these around the house. Thaks to @NTTY I know that they are still holding up well compared to newer models. Your mileage may vary, but there's no reason to fire off disrepectful emails,
