Lapping the Spade Connectors

I was just curious if anyone has tried this? If so, what were your results?

Background: I frequently lap my copper heatsinks for my computer (sand---->polish mirror finish)to get a better contact and keep my overclocked parts running a couple of degrees cooler (a measurable difference). I was think with all the debate over spades and banannas that a better contact may be worth it for speaker terminal conduction too.

Might work if the connector was solid copper. The direct gold on copper that Vampire and others use may “polish” away with lapping.

OFC copper connectors and un-plated Cardas are excellent. To keep them perfectly clean and bright, I occasionally dip mine in hydrofluoric acid followed by a water wash.

Mike Percy sold hydrofluoric acid but I think it’s been banned by both the USPS and UPS with the new security.
