True, copper doesn't rust, but it does corrode.
Brass versus copper binding posts
Greetings all. My current speakers are the Usher Dancer Mini-X DMD. I recently removed the press on tabs that connect the internal speaker wires to the drivers and solder them directly with cardas silver. I perceive an increase in sound quality, and as we know perception is reality. I planned on doing the same thing at The binding posts. I assumed they were gold-plated copper. But when I put a small drill point into the end of the threaded post the color stayed the same where I expected to see an obvious copper color. I think this means my binding posts are brass. If I’m correct that seems like a cost saving decision by Usher. Would those of you who know more about this stuff than I do agree it would be worth the time and money needed to switch to some quality gold or rhodium plated copper binding posts? Thanks in advance

I prefer solid copper binding post with heavy silver plating to prevent corrosion. See below:

Thanks again for all the help everybody. I contacted Usher in Taiwan and they emailed me that yes the binding posts are brass. The ETI items shown above were actually my first choice. I use their XLR connectors from the same family on my interconnects. Being that I would need four sets ends up to $600 to make the change that’s a lot of money. I have found a company named AECO in Taiwan that makes a similar binding posts for $60 a pair rather than $150. Model number ABI-0611 followed by a suffix of G, S or R that designates gold, silver or rhodium plating directly onto tellurium copper. All of my speaker cables are Clear Day silver with silver plated spades and bananas. So I think I will be ordering the silver plated versions. | ||||
