I have recently purchased a used PS Audio ultralink Dac. The unit has distortion on both channels in the high frequency. The distortion sounds as if the tweeters are torn. When I play the speakers with my regular Dac, they play just fine. Also there is a loud pop when the unit locks from the coaxial to the Optical mode which is bizarre. Please let me know which part of the Dac needs to be checked and how.
Also is it possible that there is DC at the output of the Dac which is causing the above ?

You might contact PS Audio to see what they think. Maybe they would even supply a schematic if you asked nicely...
Other than that, you would need some test equipment and some knowledge of electronics to work on it yourself. Do you have a DVM, a scope, and already know a lot about CD players?
