Re-wiring the listening room: Questions

You know the wire in your walls in not going to change the frequency response of your system right? Outlets won't either.

I think non-cryo romex has a sound too, 12ga is more balanced, but 10ga while better in dynamics, seems to have a hole in the lower-midrange to mid-bass. Definitely get good outlets, I'm planning to install an SR purple to see what it does for my EQ hole as compared to my Furutech GTX-R. The newer GTX-R with NCF is supposed to be more balanced in EQ.

@gthirteen are you running balanced between your amps at 12 and electronics at 9? If so, another run at 12 would be there if you need it. If you are no running balanced, plugging into multiple spots is asking for trouble.

I didn't know cryo-d romex was a choice, and thanks for the "aftermarket" cable suggestions!!!

@britamerican I have 6 dedicated 20A circuits with 10awg wire, I'm only using 4 dedicated circuits at present, but there are no ground loops, and none of my equipment is using balanced connections.

Use MC Cable (metal clad). It provides a metal shield around each circuit home run. But you must have steel bracket boxes, plastic will not work.
