What use to burn in power cords?

Hello nasaman.  Get the right adapter and use a hair dryer for a day or until it starts to melt. Half a day is probably enough. The ones I have sounder better right off the bat, so I just used 'em. and was happy they got better over time. Happy Listening!

Use the new power cord with the adapter on your refrigerator. Keep a thermometer inside and when the temperature drops 20 degrees inside it’s totally burnt in. Believe me I tried it and it works. 

John (NASAMAN) that adapter works. I used it.

I used the adapter to burn in my last power cord on the instant pot. It worked like a charm. I swear the stew was just insane with layers of flavor and amazing separation between the carrots, potatoes and the meat. The meat was dead center and was as organic as could be. 
 

Jokes aside, any of you ever heard your system plugged into a brand new Furutech GTX-D NCF outlet? And then listen to it 2 days later? Try it and then say break in is fallacy. I had a “pleasure” breaking in two of these at different times and it was exactly the same routine the second time. Rollercoaster for one month straight.
