I am using 10 gauge wire, try pulling that wire! I have 3 dedicated lines. One for digital that plugs into a PS P-10, one for my Pre/Amp (Pass Labs) and one for my subs (JL Audio F-113). All of the outlets are the Furutech GTX-R.
Spread out through the 3 dedicated lines are 8 High Fidelity MC .05’s.
I have a whole house surge protector, but when I am aware of a storm I still disconnect by turning off the circuit breakers and unplugging equipment.
