Anything better than 10 guage Romex?


I maybe moving my set up to a smaller room, but the upside is I can run shorter runs and increase the number of dedicated lines.

My question is,What(other than 10 guage Romex solid core)are others using when they have this opportunity to upgrade?

Thanks.

AudioQuest makes a power cable available in bulk, but it would be spendy. Also Romex used to make a parrellel 14ga cable for such reasons, not sure if they still do. that would provide more skin surface than the 10ga.
