Need to burn in IEC 2 prong adapter?

Like the CBC digital radio music from the digital TV box provided by local phone company. the digital TV box is free, but Chamber and Jazz music sounds as good as from my arcam cd72 when using good IC.

I have some good experience with Audience Powerchord for my cd player and int amp. All Sounds bigger, quieter. Therefore I want to improve digital radio music in the digital TV box by using Audience Powerchord as well. When I plug the powerchord with a IEC 2 prong adapter to the digital TV box, it sounds smaller and worse than the 2 prong standard power cord.(have to use a IEC adapter for the digital TV box)

Just wondering if I need to burn in IEC 2 prong adapter for 200 hours like cables? or I have to buy more expensive adapater than the one(X-port) I got from Audioparts?

Seen lots of debate about expensive PC. Today I picked 3 songs from a telrac classical Cd and did a Audience Powerchord and standard PC blind test when switching them to the int rotel amp. My wife picked Audience powerchord every single time for 3 songs. The improvement from cd player is even more apparent to us than the int amp.
