How do I choose a tonearm cable?

I’ve been pulling my system together for several months and discovered that I need a DIN to RCA tonearm cable that’s longer than the one I have.  After trying to wrap my head around the myriad of options and reading head-spinning technical threads, I’m no closer to making a selection.  

Pricing runs the gamut.  I want to make a good decision, but I’m unwilling sell blood or stand on corners to pay for a piece of wire (besides, I’ve been spending all my money on albums that I can’t yet play).   

My system has been down for months with the amps being converted from stereo to monoblocks and new caps, fighting gremlins in my preamp (which died and has been replaced), added a power conditioner, and a phono stage that’s a stepping stone until get my endgame component.  

I want to get this tonearm cable figured out.  As it stands, I have a Blue Jean Cable cable coming off my Feickert Volare 25 with Hana ML and Auris 10 tonearm but I don’t know if the BJC is good, bad or otherwise.  I highly suspect that I can do better.

Looking for advice.  Thoughts?
