Here is something to think about.
If your wire is truly only carrying DC, the only consideration is the resistance.
But, that's not likely to be the case. The current demand is probably constantly changing with program material, which therefore means it's carrying AC in some form. There's very likely unwanted currents, both differential mode and common mode, traveling where you don't want them to go (like through the AC wiring in the wall). There's also various coupling mechanisms that can add unwanted signals onto the cable that can also pollute the components connected to this DC connection. And, more.
So, you're left with a dilemma. Do you try to fix the core problem (for lack of a better word) or try to apply some mediation through tweaking the cabling for your particular installation? Both?
Once again, I am NOT suggesting at all that cables don't matter. See above. I am also NOT negating your observations. I have no reason to suspect that you are just imaging this - I've certainly experienced the same.
I'm only suggesting that you might gain more by going beyond cabling experiments. YMMV and all that applies.
