RE: what do you look for in the graphs?

"there's no substitute for analyzing potential PS filters with SPICE."

Agreed. I've never used PSUD2, but from what I've gleaned, it doesn't sound to be particularly appropriate for trying to optimise the performance of a power supply for an amplifier. As Tre says, the kind of time dependent load that a class A amplifier imposes on a power supply is not the kind that can be particularly well analysed if the only time-dependent thing one can model in the power supply software is the effect of a stepped load. LTSpice is really much more versatile for the kind of modelling that will realistically show the behaviour of the power supply when the amplifier is playing music. I don't see the point of trying to use PSUD2 for this kind of application.
