TX-103 break in.

I recently purchased a pair of Mu MC Step Up transformers by Bent Audio. Does anyone here know the break in process for these. I was able to find this by Thorsten Loesch but I don't understand it, doesn't quite make sense to me. Maybe a more simple explanation would be helpful. 

From diyAudio; Break-In Instructions from Thorsten Loesch

This worked very well for me, so I recommend it highly. This is what Loesch wrote, with a little editing:

"(The TX-103)... will require a substantial period of "forced burn in" to give it's best, simply because the magnetic core is huge and will not see much magnetisation with normal MC signals. Please consider connecting a CD-Player to the secondary (Output) of the TX-103 and then terminate the input with a low resistance resistor (quality uncritical), I'd say 27 Ohm when connected for 14db gain, 6.8 Ohm when connected for 20db gain and 2.2 Ohm when connected for 26db gain. Leave with a highly dynamic, wide bandwidth signal CD to play for a week or two. I would use music, but I'd expect pink noise to work well too."

Thank you for responding. I'm pretty sure I am following what you said. What I don't understand is connecting the CD player to the output of the transformer, then connecting the RCA/resistor to the input. Isn't that backwards? How is the transformer receiving a signal
if the CD player is connected to the output?

Got it, thank you very much. Connect my CD player to the inputs on the SUT's, play an appropriate CD on repeat (Classical). On the resistor, does the value matter?

@charliee: I see from your second post here that you must have done poorly in your college physics course. Not knowing how a transformer works! Willing to believe in any old Mumbo-Jumbo!
