Cambridge Audio CD Player Has Died


I have a Cambridge Audio Azur 840C CD player that is roughly 15 years old. A year ago the left channel went dead & was subsequently repaired. However, yesterday the audio output completely died (no sound whatsoever). Although the unit has served me well, I am reluctant to continue to put more money into repairs of an older unit.

That being said, I have a question for those of you who have more expertise than I. Is there a discernible difference in sound quality between high-end CD players & those more moderately priced? Although I do have a high-quality audio system, I would prefer not to spend a lot of money on a new CD player unnecessarily.
Thank you so much.

Is there an method to determine whether the problem lies with the DAC or the transport that I can do myself?
Chances are the transport is still good. You might get a cheap DAC that you can use to test the Cambridge.
Well, out of curiosity I turned on the CD player a few minutes ago. At the moment it's working, but there undoubtedly is an issue. Maybe heat related? We'll see.
I disagree that there's a good chance that the transport may have outlasted the DAC. Typically, mechanical transports wear out or the laser weakens. DACs being non-mechanical usually don't wear out.  By all means, check the transport with an outboard DAC if possible, but I'd bet money it's the transport.  Have you notice an tracking problems?
