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.
I can't go on and I can't go back, I don't feel so matter of fact,
I tried and tried to make good sense, What's the good to try it all again?
