"With switching mode powersupplies (as in the KPA500 and 1500 and most of the solid state amplifiers with ps included) usually no further measures are necessary or would help in that respect as most SMPS have soft start circuits included."
KPA500 nominal 60 V PSU is not a switching mode supply. About one quarter of the chassis volume is occupied by a toroidal transformer and its output goes to a bridge rectifier.
