I moved house at the weekend. I disconnected all the outputs from my tech. I disconnected the other ends from their associated tech. I picked up the whole cable jungle (which helpfully came up in one semi-solid mass) and deposited it in a box. An ML110 server box. It filled the box. At the other end, I lifted it out of the box and deposited it behind the tv. I plugged all the ends in.

It all works perfectly. Not only that, but I saved many hours of futile untangling. These things get in a mess. It’s What They Do. IT’S ALL THEY DO.
