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.

Impossible to say until you try it. It is quite far from the active components themselves, and the only way to find out if it makes a difference, is to try to get it done.

The question is valid, but also obscure enough to start a verbal war.


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

As teo_audio says, try it and let us know. Also, isn't the ground plate on the SR grounding blocks copper? Perhaps SR can share why they chose copper over aluminium? 
David, I'm referring to the electrical panel bus bar.  In my Square D Homeline electrical panel, both the bus bar and grounding bus bar(s) are aluminum.  I have ask a few manufactures and I get a somewhat mixed response.  One says it's huge and the other manufacture says it's a slight improvement.  I am asking the question because I was quoted $1850 for this and I estimate there is $600 in material.  I'd rather evaluate the inputs before I take the plunge.

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.
Well, Aluminum is certainly cheaper than copper that could be a motivation.
BTW: It's a harness not a "loom".
A loom is a machine to make fabric.
A harness is something to focus brute force in order to do work.
