comparison of different dedicated AC line types?


Im getting ready to move my audio system to another part of the house. I'm wondering if anyone has had any experience in comparing a regular dedicated 12 Ga romex line feed to a greenfield (flexible metal conduit) dedicated 12 Ga feed line? Also has anyone tried to terminate a dedicated line with an IEC and plug it in direct to your equipment?

Romex, Home Depot.

Southwire, Romex.

Cerrowire, Home Depot.

Cerrowire.

I doubt if there is an ounce of difference between the two manufactured brands. Note it appears Home Depot sells the Romex brand in a 100ft roll and the Cerrowire brand in a 50ft roll. You may have only needed 50ft or less. That could be the reason the electrician bought the Cerrowire brand instead of the Romex brand.
