An LOD to RCA may be a better deal in the end. I can't say that I know since it would be something you would have to decide for yourself. I know for myself I made a few cables and and if I were to make one it would depend on how practical for me since I am likely to use it for other things.
I can and have built LOD to RCA cables. I use Canare and Mogami Cable and Neutik RCA's in a variety of colors. I sell them pretty much at my cost, I just do it as a hobby for friends on Headfi. Check my feedback.
This is one that I made with a mini, I can put a LOD on the end instead.
