Hi all,
I have a mcintosh caraudio dac
Its a bit noisy when playing music. Its a strange noise that seems to play along with the music.
So far i've opened the unit checked the supply voltage and checked the pin lay-out of the dac chip which are 2 times Burr Brown pcm1704. I have checked the supply voltage on the Pins but cannot seem to find the issue.
Im not a full blown electician, i just know a bit of the basics.
Anybody that can help out here?

Noise that changes with the music is called "signal-correlated noise." Could be from a bad connection somewhere, especially if it didn't always do that. Also is there a volume control it it, or is it just dac with some kind of digital input stream and then it output some analog music signal?
