Dedicated 20 Amp Line for Audio

I used this https://www.gigawatt.eu/produkt/in-wall-cable-gigawatt-lc-y-3x4-mk3/

for my dedicated line, 11ga, flexible and directional. It ssounds incredible.

I would like to add that I did run 2ga wire to a sub-panel as close as possible to my listening room. This enabled me to run the quality Giga cable a much shorter distance and then the size doesn't matter as much. Ohms law, shorter distance means less resistance.

You won't be disappointed in the LC-Y EVO Cable. It is directional so tell the electrician so he doesn't install it backwards. There are arrows on the jacket. It will need a little break-in time.
