If you have a large cap at the input it will draw current spikes when it recharges (the smal time when the voltage over the cap is lower then the woltage from the rectifyer) this will produce a lot of HF noice on the powerlines not to good..

so why not try to prevent these spikes from the begining rather then try to filter them out with extra LC Stages?
