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?

Thank you elizabeth, I appreciate your help. I will be ordering from partsconnexion tonight.

roberjerman, I did not take physics in college, so I guess I am screwed. But when it comes to SUT's I think I will be taking advice from folks like Thorsten Loesch, Arthur Salvatore, and my new friend here elizabeth. But thank you for trying to help.

racamuti, I suppose it's possible that it was broken in, but I have my doubts. They should sound better than they do. I ordered the resisters today from partsconnexion and have the RCA's ready. I have a ZYX CPP-1 Pre-PreAmp to use while the SUT's are out of the system. 

Interesting that you are not using them as their main benefit is to improve playback performance rather than provide gain, you can get the gain you need from your phono section as you are doing now.

chakster, I think its an excellent device, it's as good or even a little better than the TX-103 SUT's. To answer your question, no I have not opened it up. But I have considered having SoraSound send it back to Japan as there is an upgrade for it. I am not familiar with the Luxman SUT.
