How long for an HDMI cable to break in.

@muvluv light doesn’t travel thru copper wires. With your level of expertise in this field you should keep your thoughts to yourself. 

@bigtwin 

Not in this car, although some years back I had a 1972 GTO that had many options electric windows rear window, D fogger blower tinted glass AMFM with a console and factory eight track mounted to the console same colour of course matching the dash and console school bag brown I called it or sandal really. The sound system was more expensive as an option than a person upgrading to 455 requiring the 12 bolt differential can you imagine? 

How does a cable get "burned in"? Inquiring minds want to know..

@muvluv ,

I'm about to purchase a fiber optic cable.

What type copper do you recommend?

LOL... Beryllium Copper. It's da' bomb
