"Please also note that there is a BIG difference between a true choke-input power supply and a power supply with a choke. The latter is more of a gimmick, created largely to give the marketing department something to spin."
This is truer for a lower impedance high capacitance PS for SS and OTL amps. For high impedance amps, OPT style tube amps, the CLC filtered L component is much more useful: smaller lower current chokes, a higher order and more complete filter for 100-120 Hz as especially SET amps have poor PSRR. Less important always with balanced design.
