phono preamp break-in machine

Buying a new phono pre- amp. My dealer says there is a machine that receives a cd signal that is playing a break-in disc. This signal is fed into the phone preamp and "brakes" it in. This method by-passes playing hundreds and hundreds of hours of vinly on ones turntable. Dealer can not remember the name of this machine. Anyone know the source where I can purchase such a machine if it exists? Thanks for your help.
