Dedicated Line

I have experimented over the last several years with various wires to use for dedicated 20-amp circuits. I have the following wire in use in no special order:
1) 10 gage Romex
2) 10 gage UV
3) Belden 83802
4) Virtual Dynamics 10 gage BX Cryogenically treated with Cryo’d circuit breaker. *

To my ears on my revealing system I hear NO difference between (1-4)! I think simply using a dedicated circuit with 10 gage copper makes the biggest difference.

* There might be other positive factors to using cryogenically treated wiring besides sonics. It might lower the operating temperature of equipment.

Hello, you both mention 10 guage wire -is this a standard, a rule of thumb type of thing? Thanks.

Strands in cables react with each other in a home wiring scheme. Solid core is best with 60 cycle AC period. OLD OLD wiring was at one point stranded. Solid copper lasts longest and will make the biggest difference.

I will try the solid core,but hesitate because it will be bent as it snakes it's way from the panel thru my floor joists as I have a basement listening room. I used 2 runs of Carol 10/3 90c(ul)water resistant p-7k 123033-600V from the panel along the floor . One to Hydra 2 for the power amps and one to a Furman 20 amp balanced power conditioner.There are no bends when cable is run on the floor with the Carol, and it is safe(used at outdoor concerts over wet grass).Can we say the same for the solid core romex? If I use the romex what do I do if I run it along the floor?
