Wouw, I don't even remember writing that original post. I must admit that I would never buy the cable today. I can't remember the price in DK at the B&O dealers, but it was ridiculous for what is only a couple of plugs and some cable.
If you have any experience with a soldering iron it shouldn't be to hard to make it yourself, Peter Pan has a lot of different wiring diagrams in this Danish thread, but of course I can't find the proper one right now.
