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

Jitter look up the transverse shear velocity of the metals you mentioned..add to that list aluminum and all their many cousins. Shear velocity and their polarities are a big key to how things sound and why they sound so different. Tom
Will we ever find out who, in fact, hired who and what really happened in that saga between Robert and Michael Green? We have been kept in suspense for two years.
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..."
