IC Failure


I recently had a failure in one of a pair of very high-priced, prestigious IC's. It simply has stopped transmitting a signal. I have swapped them out with other IC's in different components and definitely have isolated the problem to the IC. Both IC terminations are intact and solid. Can an IC short out?

Additional info: I just had the caps in my pre upgraded to Teflon, and this failure happened when I tried using my DAC. The suspect IC's ran from DAC to pre. All pre inputs, including CD and DVD, work fine with other IC's.

In almost 40 years of audiophilia I have never had this happen. Thanks for input. Want to hear from the cognoscenti before I go back to manufacturer.

Did you try doing a continuity test with a volt meter on the cable? This will tell you if there is a short. It's possible and it's happened to me with a set of cables.
More than likely the cable has an open connection.
More than likely at one of the RCA male plug connectors.

Bending the cable too sharply near the end can cause a connection to break free.

If the ends are the type that can be disassembled, carefully take the connector apart and inspect the terminations of the hot signal and return signal ground wires.

You have a 50/50 chance of finding the bad end the first time......

Do you have a multimeter? You can do a test for continuity across your suspect ICs.
