Any specific reason why some audio company's use tantalum caps for psu decoupling close to opamps?
I know tants have the tendency to go short after some years. Euphonix for example (cs2000) had tantalums all over the console next to opamps.
It's really funny when they go short, console doesn't start. Taking all modules out one by one and than start looking for the leaky bastard.
Right now I'm reading the opa604 datasheet:
Is there any reason for this ?
(other than bugging the maintenance guy in ten years)
Just wondering...
thanks
EDIT: btw, I'm aware of WHY these caps are there just not sure why they use(d) tantalums.

Applications with noisy or high impedance power supply lines may require decoupling capacitors close to the device pins. In most cases, a 1μF tantalum capacitor at each power supply pin is adequate
