It's been a couple of month I randomly end up with distorted sound and unbearable squeaking after 1 or 2 hours of listening .
I thought it was my Denon DCD-1520 CD player that was getting old until the same phenomenon began happening more and more oftenly.
The problem turned out to come from my CX-1000 preamp DAC. I was able to make sure that was the problem by switching digital inputs (both coaxial and optical) and switching CD players on the same inputs (I own another Denon multiple CD player with digital output). The problem never happens on analog inputs.
The squeaking sounds begin after a quick deterioration of the sound quality followed by an almost complete fade out of the music. It sounds like some digital parasites you can hear when you have bad reception on your satellite receiver. I have to turn off and on the preamp to solve the issue. And then again, same problem after a couple of minutes of listening.
I think that the issue is more frequent when the preamp is warm.
Before thinking of opening up my CX-1000, does anybody know if there is a possibility it's something simple like a capacitor that was blown? Or is it most probably the DAC board?
Thanks!
