help with din to rca cable for creek amp?

Correction: I just checked some Neutrik catalogs and I noticed that they are NOT the same as DIN's. I assumed that Neutrik also makes standard DIN's.
My previous advice does NOT apply to the Neutrik. It applies to the connectors found here: http://www.action-electronics.com/ppdin.htm I was talikng about item "DIN460005P" (first one on the left, in the photo.)

You can either go with Sugarbrie's offer, either pick a cable of your choosing and if it doesn't work, try to modify it. DIN cables were meant (among other things) to be used as a single link between say a tape deck and another. There are 5 pins on the connector; the one in the middle (say no. 3) is the ground, which is common for both input and output. The reason for your cable not working is probably that you need pins 1&2 to be active, while the cable has only 4&5 connected, or vice-versa. (if it's not a "double" cable the other two pins are probably empty). If you're good with a soldering iron, you can customize just about any cable you like to suit your needs - but you'll have to "destroy" one end and add your new connector. Hope this helps.
