There's been some talk about what to do to minimize stress on the Line In jack. I received my custom made cable from Justin Marinoff a couple days ago. Here's a picture of my simple solution.
I'm just gonna keep the cable connected to the unit all the time and keep the rubber band snug around the R-09 to keep the cable from yanking on the jack.
Here's a link to the Retail Space, where I posted a little bit of detail about the cable.
