Question on Cardas Frequency Sweep & burn in LP

I use the Cardas cuts 2a, b, and c of the first version LP to "wake up" cartridges I have not used in a long time or to break in a new cartridge. The results seem to be beneficial, emphasis on "seem". But how could anyone have anything but a subjective opinion about the relative merits of each of the three break-in LPs you mention? One cannot do any sort of controlled comparison, because any given cartridge, once it's been run any single one of the 3 discs, has been changed from its new or unused state. It's kind of like wondering whether you should have married this girl or that girl (or guy) post facto.

Stressed? Me?
While my audiophilia does cause occasional stress, it is never around whether I am using the "best" test LP. I think Mr. Cardas realized that the best way to enhance the profits from his first test LP was to make another.
