Tray cable is an NEC wire designation. It differs from standard THHN wiring in that it uses multi-strand tin-coated soft copper. However, some use standard THHN conductors (as does Romex and BX). Whether TC Type power cable is superior to Romex from an audio perspective, that's a debate yet to be heard. One important thing: be mindful of your local electrical codes - TC wire cannot be suspended as an open cable like BX or Romex. It must be run in a cable tray system, which can add a significant cost to the installation.
Dedicated AC line with tray cable
I recently had an electrician install 5 dedicated lines for my audio equipment. I asked for #10 rommex, but he indicated that he could get "#10 tray cable (or tray wire) which he felt was superior to rommex or thhn. Anyone familiar with tray cables/tray wire, and your thoughts on using it instead of rommex or thhn. Your comments are greatly appreciated.
