The Purist Audio Design system enhancer CD contains all the sounds necessary to completely break in the speakers, wire, caps, and crossover parts. Months later, after you have forgotten about your break in problems, a "touch up" of 60 minutes with the Purist CD will amaze you. It is also possible to hook up a CD player to put the Purist CD through the clips where the phono cartridge hooks up. (Cartridge disconnected!) That way you can leave the CD on repeat and get massive hours on the tonearm wire, connectors and interconnect to the phono stage without "tending" your record playing machine and wearing out an expensive stylus. In other words, the disk is valuable beyond your current need.
