Some great responses about I got a few good laughs!
Since we are a manufacturer nd a repair service when buying any audio component used you have to determine if the parts are available. Anything can be repaired if the parts are available. As per your question, I would get a used Cary 306 S SACD player. In stock for it has below average sound IMO. But once you upgrade the caps and some resistors in the power supply, the sound changes dramatically and will complete with anything you have heard. The upgrade includes over 100 parts if I remember correctly. We were blown away but the upgrade.
Happy Listening.
