There are two ways to do this. First as suggested by bigwave1 is to use the Granite Audio CD, set on repeat for the single moving coil track. Second, get an inverse RIAA network from Hagerman Labs. You run the output of your CD player using any CD on repeat into the network. The output of the network goes into the input of your phono stage. With both methods keep the CD player and the phono stage on 24/7 and in a few weeks you will have a broken in phono stage. I have used both methods with great success.
