Sound differences between Copper and Aluminum Bus Bar Electrical Panels

Where exactly does this end, and what exactly are you training your neural paths to do for you? 

I mean, if this is all that, you need to go fully off grid, and design some audiophile grade inverters. Maybe just go full battery powered listening room. But come on!

Even if you could hear differences, and the ear/brain might, this is something you are training your ear to do for you. You are choosing to attempt to listen to things no one else can. Is that really your goal? 

I used to be a projectionist and I learned to listen and view each frame critically for noise and dust and scratches, making it very difficult to watch a movie anymore. Don't do that.

It's a basic question.  Yes there are probably better ways to improve your system.  I'm interest if anybody went this far to do it and what the results was. The Audio Bacon guys did this but haven't responded to this question on their website in one of the review responses. 

Since posting this, I have seen that the incoming utility power line is heavy aluminium and the conduit from the meter to my electrical box is heavy aluminum so I think it's not worth pursuing even if I do it myself.

mikeg:

There is a tremendous amount of electrical noise generated by the electrical panel. I think the best beginning step to improve the situation is to reduce noise generated by the tens of suboptimal connections in the panel. I used the Total Contact product on the approximately 80 connections within my panel and have had a major improvement in sound. There is a discussion about Total Contact on the members review forum.

Please call me if you would like to discuss the topic further.

David, Check the TC thread.  I made the last post.  

What’s interesting is, when my contractor went to source subpanels here in Austin for a "from scratch" install, the supply houses claimed they had Square D with copper buss bars, and upon examination, all were aluminum. When I was in NY metro, it wasn’t a special order and readily available at local suppliers.
I think I wound up w/ Cutler Hammer w/ copper bar.
I never compared aluminum v. copper, just followed what i understood to be good practices. (I know, the way of sheep). But, the electrical subsystem I had the contractors install in the past year is great; ironically, even the ’dirty’ power here (without the big iso transformer that got installed in the backyard) was pretty quiet, even though I’m essentially "in town" in a residential neighborhood. I think there are a lot of variables, starting with the quality of the power coming in from the pole, and then following good practices--I am a big fan of @jea48 ’s input on this board, b/c he isn’t proposing ultra expensive audiophile solutions, just basic above code quality and practice.
