I’d have to look to be sure, but I think I got mine in the summer of ’20 and I’ve only had two anomaly’s. I bought a used red book MFSL copy of Linda Ronstadt/Simple Dreams on ebay and it would not recognize it. My previous red book Rega transport did recoginize it . . . I gave that copy away and bought another on ebay which my SA10 did recognize. In approximately four years, that was the only CD it would not read.
Then, and I don’t know how long ago this was, but probably easily over a year ago, I put a CD in and hit ’play’ and it made a horrendous digital static sound. I quickly stopped it, tried another CD , and it worked great. I cleaned the CD that it offended on, tried it again, no issues. That has never repeated.
Also, I bought one of those little carbon fiber discs that Herbies sells that fit over the top of a CD and are supposed to "make it sound better", and my SA10 didn’t seem to like it (made strange noises as it was trying to read it, but then after it could read it, it would play, so I quit using that Herbies CD thingy.
That’s really been it in four years. Knocking wood.
As an aside, my insurance policy arrived today. Prompt shipping. But I do think that considering what it was that they were shipping, they could have done a better job of packaging. I think they could have used a box with bubble wrap instead of a padded mailer.
