If you build your own power cables, instead of just inserting the stripped wire into the connector - try crimping and soldering copper spade connectors on to the ends and then tighten down as hard as you can.
I didn't use anything special - just spades from my local parts supply - but they are copper and the correct gauge for the wire and the solder is good quality lead-free for electronics use
The improvements in dynamics and fine details was very noticeable.
The first cable I tried this on was a 10gauge furutech cable which was proving difficult to install a connector onto.
The other advantage - none of those little rogue strands of conductor that do not go into the hole that can cause serious problems :-)
