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.

Neal, do as Jea48 suggests. I would add to turn the multimeter to measure Ohms, the symbol shaped like a horseshoe to measure continuity. Any setting in the ohm range will suffice. Make sure that your leads are plugged into the multimeter correctly to measure ohms (red/black and plugged into ohm/volt not amp). Continuity = close to zero. If there is a break, your multimeter will probably read 1 or OL.

I've had a solder joint break on an inexpensive pair of Monster interconnects years ago that caused an interconnect to "go bad". Since it was cheap I just soldered it myself. If the cable is expensive, I'd send it back to the maufacturer for repair.
