Stainless Steel Binding posts on speakers?


Anybody have any thoughts about using this material for binding posts? With regard to conductivity/sound quality and the like?

I hear ya'. The reason I ask is Legacy uses SS for their binding posts on the Whisper XD's and stainless is rated VERY low in conductivity vs. copper and gold plated copper. Seems a very odd choice! This is a GREAT sounding speaker and I wonder how much better it COULD sound if a more 'industry standard' material were used?
Roxy54. Nope. Definitely not Rhodium plated brass. I have an extra one of them that was defective and took a 3 corner file to it to scratch the surface...same steel grey color inside. And the non-magnetic type. They are pretty things and very beefy, but definitely stainless steel.
Well there are certainly dissimilar metals involved here in that the posts are SS, the rear anchor nut is galvanized steel and the spade connectors on my cables are Rhodium plate over copper. And these posts are quite substantial, they are .710" at their widest with a 2.5" ( actually the metric equivalent) overall length and a 5/16" threaded shaft. Big chunks of metal! They are beautiful, but would not have been my choice for a high end speaker.
Interesting comparison chart showing how far down the ladder SS is conductivity-wise compared to the other more commonly used materials in High End Speaker binding posts.
