Simple way to burn in phono cable w/ din ?

Thank you Albertporter. Though I've never soldered anything before, tinning the ends seems easy enough, but I'm a little confused as to where the right and left "pins" are inserted into the female din. One site I visited shows a head on view of the female din, with the holes at the peripheral of the din located as follows: hole #1 is at the lower mid-left, then upward clockwise is #4, followed at the top by #2(ground), next is #5 on upper right, then #3 below it is at mid-right. Also, please pardon my ignorance, but when I'm using a cd player or any other burn in device (I have a FryKleaner Pro) does the preamp stay on or off, and either way, does it remain disconnected from the amp[s] ? Thanks kindly for your assistance.

Think I've got it. A chart indicates in/out/ground numbers (pin holes in female din) associated with various components listed under peripheral/connected. All ones and threes, whether in or out, are "left" indicated, while all fours and fives, whether in or out are "right" indicated. So, left "pins" from rca cable are inserted into holes one and three of the female din; right "pins" from rca cable are inserted into holes four and five in the female din. Am I correct ?
