I have the Purist disc also, but for phono preamps (and stages) I think the disc made by Granite audio specifically for that purpose is better. It contains the RIAA frequency pre-emphasis that is applied to records and then de-emphasized in the phonostage.
No CD can work on circuitry it doesn't send signal thru. Even the Granite requires that you hook the output of your CD player (with its own volume control) to the inputs of your phono preamp/stage.
Personally I think using the sweep tracks on a record like the Cardas regularly keeps everything (including the cartridge!) in shape.
