Twist AC and DC power hookup wires or not

[sbelyo]

So I don't make mistakes in my latest build I was wondering what is reccomended most.

 

Should I twist the AC power leads on a torroid being used in a DAC?

 

Should I twist the DC power hookup wire that will go from the PSU to the DAC board?

 

I'm assuming I should always twist the signal wires...

Twisting or braiding AC disrupts the magnetic field so it's a good idea.  With DC it's not crucial and could even be a bad idea (capacitance)

That's what I thought.  Thanks
