Replacing driver screws with brass screws


There was some discussion about this on Millercarbon's thread about the Moab speakers, and I wanted to pursue the subject further without interfering with his thread.
As I stated there, I have heard about this practice for quite a few years, but never tried it because it seemed like one of those lunatic fringe ideas; and even though I actually really enjoy trying tweaks, and have found many of them effective, I just was not prepared for what this one did for the music coming out of my speakers. 
Specifically, it improved the detail in ambient trails, focus in general, complex harmonics in voices and stringed instruments, and instrumental separation. It is not subtle, and it is immediately noticeable.
So, I am curious to know how many of you out there have tried this, and what your experience has been.
Thanks, John

Sorry guys, I deleted my last post. I didn’t want to publish that in my world it is not conceivable that anyone could or even would want (to be ? enough) to hear the difference in sound of different metals holding down a speaker. You called me out on it, so there it is.
"...the difference in sound of different metals..."

No love for wood?
Mr. Glup has questioned several times the appropriateness of using wood screws to secure speaker drivers to the cabinets.  As well as the sonics of using different wood variety screws.  His inquiries have not been heard or addressed? 
I had a few more.

Different, let them be metals, screws on, for example, wooden, aluminum, granite, etc. enclosures. It seems like those interactions might prevent that only one type, brass in this case, is "the one". In short, if different screw metal matters, why wouldn’t different materials the screw is attached to matter even more in this story?

Then, are there screws on electrostatic speakers? If yes, do changes in their material also matter for the sound?

I know that title is "Brass screws", but these questions are not that removed from the discussion. They are only a developmental step above "brass or no brass".

I know what you are thinking. "No bras(s)".
It is not necessarily the brass vs ferromagnetic steel screws but screws better bonding speaker frames to the cabinet.
