Is 50v cap too high for an amp with 32v power supply?

They doing it intentionally in order to implement planned obsolescence policy for home electronics. 
Manufacturers are not interested in reliable and long life home electronics, because in such case they will lose profit.

if you build something to last 10 years that is going to be replaced in 3 years anyway, it'll be too expensive and no one will buy it

Below is an example where I probably should have used even higher voltage replacements just to get a physically longer part for better mounting.

Love that 70s-era electronics assembly. Just like Disco music, it brings back old memories.

Doctorandus_P:
Is there any indication the 35V caps are failing?
(I am assuming we're discussing some Electrolytic Power Caps here, it has not been mentioned explicitly)
32 V is just fine for a 35V (or higher, the sky is the limit) rated cap.

These were Broadcast level equipment---10 years is incredibly youthful in that environment!
Sony designed stuff that would handle component value changes.
Too expensive to do that for consumer stuff!
