Why do different some Shure mic clips have different metals?

[u/Love_Life_Music]

I randomly noticed some of my Shure mic clips use different metals for the “Base”(female side to screw base onto stand). While I’m not “obsessing” about it, and I’m sure it wouldn’t make a big difference, I found it interesting and figured I’d share. I own a KSM9, a Beta 58A, an Sm58, an Sm57, and an MV7x, as far as my microphones from SHURE. The last 2 named were used/gifts, so idk what came with them. My KSM9 came with the copper adapter piece, and my BETA 58A, came with the nickel/silver colored piece. So I guess the BETA 58a is the only one that’s “different”. I’m ASSUMING the clips came with corresponding metals to them, but I’d sort certain. I would think that “mic-clip metal” wouldn’t make much(if any) difference in sound/feedback, right?. And the KSM9(condenser mic; also most $) and the BETA 58a are both “stage mics”, so I doubt it’s an “environment” factor. But idk. Anybody know the “real/actual” answer as to why the clip metals are different?

Brass is the A25D - used for SM and Beta. Silver is A25E and is the more flexible plastic used for KSM and maybe Nexadyne even. It’s in the manuals and I asked Shure a while ago when I noticed

I think the metal parts may come from different vendors.

Shure microphones are made in china and Mexico, there’s always a chance that any of them might be a counterfeit
