Dis all you need are mating connectors that plug into the CD's outputs; this could be RCA's, or XLR's if balanced outputs are used. If RCA's, just solder a low-ish load resistance (maybe 1000 ohms or so, low power resistors 1/4 watt or 1/8 watt are fine, & tolerance doesn't matter 10% or even 20% who cares - get some cheap ones) from connector shield to tip. If you have the Cannon plugs solder from pin 2 to pin 3. You could increase load current by dropping to around 600 ohm terminations.
Sometimes you want to break in a cable instead, or even simultaneously with the player breakin. To do this you need the mating connectors which wil fit onto the ends of your cables, then place the termination resistors appropriately. XLR's if not avail from Radio Shaft then try Michael Percy Audio. Just get the cheap connectors unless you plan to re-use them for a DIY cable project down the road.
