Question about Denon Audio Players & Recorders
You didn't mention what the source of your material is that you are inputting to the Denon and that may make a difference.
If you have AM/FM selected, the problem could be in the receiver.
If the source doesn't matter and you have distortion from any source, then the problem is in either the output amplifiers (which may be larger modules) or in the power supply.
Not being able to hear it, it's tough to exactly diagnose but your description sounds like 'clipping distortion' and this can happen because of too low of voltage from the power supply.
This can again, come from a failed voltage regulator IC or from capacitors that have decayed and are not filtering as they should.
Any good tech should be able to pinpoint it better after hearing the distorted output.
While researching that model, I saw dates ranging back to 2003 and if it has been used a lot, this is long enough to have failed capacitors since they mostly come from China and there were millions of them made with poor electrolyte quality causing relatively early failure. I have US made electrolytic capacitors that are well over 30 years old that test close to their new values. Those from China have a lousy track record.
