Not sure about cables running in, but you may need a few days to get used to the sonic difference that odd "audiophool" wires introduce. As said above, if you like the results, then fine.
I rather liked and promoted the theory that a better wire should "sound" similar to a basic cheap one, just clearer all through the range. that's what I find the MG HD cables do in my system, developing the basic qualities of my home-made and bought-in "cheap" wires.
Tear down these walls; Cut the ties that held me
Crying out at the top of my voice; Tell me now if you can hear me
