To those who want to understand, why it’s better to turn off your amps, here it is simply as possible.
(as
they like to be drained and recharged otherwise a false permanent
"empty floor" happens and your electrolytic power supply caps won’t have
the uF storage ability they once had when new
That is not what I was told by an engineer from Cornell Dublier. He told me that to get the longest life the cap should remain charged, and otherwise kept at a low temperature- heat kills electrolytics. If the cap is experiencing high ripple current, this will cause it to heat up a bit- so in such cases it will run longer if shut down and allowed to cool.
In the case of a class D amp, the ripple currents are quite low and the amp tends to operate at a low temperature, so leaving it on all the time is fine insofar as electrolytic capacitor life is concerned.
