I was involved in the discussion about “Good PC Power Supply“. Then, I suggested a small trick to wrap the power supply cable with aluminum foil (you can find it a local food store, usually to wrap food on the microwave).
After wrapping it with aluminum foil, I suggested to use heatshrink to wrap all the cable (and make it looked good and professional). One of my friend, Bang Rossi, tried this method on his PC. Below is the photo (hope you didn’t mind I put the photo here;). Thank you for the sharing, man!
A little bit messy (because he didn’t use heatshrink), but according to him, it worked good. Good dynamic and better sound stage. Wanna try yourself?
