Configuration to Prevent Ground Loop for DIY IC

Just made a couple ICs today for practice, but I just realized that I may be getting some ground loop between my source and destination. I'm using Canare StarQuad Mini, terminated by some Neutrik mini plugs (damn, those were hard to get on). In terms of the connection, I'm using the two white wires for the signal and intertwined the blue wires, connecting them both to ground on both ends. I haven't used a multimeter to measure the resistance between the two ground sleeves, but what configuration is recommended? I read about using the shielding on one end as the ground, but what's the general consensus?

Also, I plan on ordering some new plugs (ones that actually fit Canare StarQuad and StarQuad Mini). Does anyone have recommendations? I'm looking for RCA plugs as well as mini plugs.

 

Also included some pics of the cables, seeing as they're my first (the techflex and heatshrink jobs were pretty horrible).

I would suggest measuring the cables and make sure there is no malfunction in the build.

What measurements specifically would you take? Also, I have access to a o'scope; do you think it would be beneficial it to compare an input and output signal?
