15amp / 20amp PC's and Conditioners?

Another begginer's question for someone: If my amp (Krell 300i) and cd (Krell 300cd) recommend 15amp PC and conditioner,does this limmit my options in PC's and conditioners since some of them seem to be rated 20amps?
You can go higher on the rated output of the power
conditioner but not lower than the rated output of
your amp. In fact, I'd recommend the higher rated
power conditioner just to be safe.
