A single L-C filter when handed a step-change in current draw is going to ring a bit. I think that the OP was looking for a realistic means to model the amplifier circuit. Not that the step change in current is not useful, but it has limitations. For example, when run w/o a turn on delay, the difference between a resistive load and a constant current one is about 100V on the initial peak.
I am fairly confident in saying that an L-C filter, when given enough capacitance will work quite well. I'd further the Class A bit, with the addition that a PP Class A is going to vary its draw from the PS hardly at all compared to an SE one. The SE being roughly constant when averaged over a complete cycle vs. nearly constant at any given part of it.
When adding a second L-C stage, the step change in current test can be quite useful. I recall a linestage PS I built( and then Sim'd ) that rang at about a half a Hz...nearly no ripple though...LOL
