What use to burn in power cords?

Adapter and run your fridge for a week or two. 

What power cable?

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.
