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

Peter is owner of PBN Audio. He is very knowledgeable. He builds everything from speakers to amplifiers. Not too many people in this industry that knows more than him.
359/379 Peterbilt, aluminum nose. A true classic. I used to be in charge of 118 359s, and 26, 379s.. That puts a date on me for sure.. All Cummins power. 

Then I went HEAVY duty..
