Sound differences between Copper and Aluminum Bus Bar Electrical Panels


I have a Square D Homeline electrical panel that has an aluminum bus bar and I'm wondering if anyone hear went through the trouble to change the electrical panel to a copper bus bar type such as the Square D QO or any other manufacturer.  What audio improvements were heard going from aluminum to copper????  My system consists of top end components with a full loom of SR Galileo UEF cables, SR Active Grounding Block SE and an SR Powercell 12 UEF ac power conditioner.

Good question, Mike. I’m assuming you are referring to the grounding bar in the panel?

The neutral bar as well as the ground bar in the Square D QO panel and Homeline panel are made from an aluminum alloy, not plated copper.

 "The neutral bar as well as the ground bar in the Square D QO panel and Homeline panel are made from an aluminum alloy, not plated copper".

My search on the internet shows the Square D QO panel as having a copper bus bar.

That is correct. The two hot bus bars, and breaker connecting ties, are made of tinned copper.
