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

cd318,
"Who in their right mind would consider trying this out on a pair of Harbeths, Revels, Tannoys, Wilson’s etc?"
Are you really serious? It's just a screw! You can change them, and change them back if you don't like it.

As far as you're concerned nonoise, if you think that everything audible is measurable, you're the silly one, and so is the jollygreengoofball.

@roxy54 ,
I don't know where that came from. I never said it was measurable, just tested and heard and theorized about, just like jollygreenaudiophile2 stated. 
Did you get up on the wrong side of the bed today?

All the best,
Nonoise

Not at all. He asked if I had measured it, and you apparently support the idea by pasting his quote. Pretty plain to see.

OMG. I. Was. Supporting. You.

He also went into detail about how they listened and heard and theorized as to why. At no point did I paste his quote but maybe this will do:
Ok, "My turn"!

And please feel free to look this up!
There are several reasons replacing the screws with "Brass" will change the sound of your system. But it needs to be of the "Cast" variety.
There is actually, a single "published" study by a well known and very well regarded "Ivy League" university as well as many others currently, "Un-published" and still, um classified. "I know of at least fifteen of these".
The un-classified study is not hard to find online. Just ask the right question of your browser!
And ALL of them were commissioned by the federal government with most but not all paid for by military research entities. Also they were all offered, and completed within the same 12 year period. They were to study and classify all known alloys with the goal of ascertaining the effects on electromagnetic fields when different alloys are applied to said fields. They found some odd things. One of which is that "Cast Brass" works as a mid-range frequency, resonance and free harmonic filter.
It's been awhile but I believe the range was roughly 1.4Khz- to a little over 5Khz. The brass could also be used as a type of particle boundary. They can also help stabilize a field if used in a certain fashion. And since the voice coil works how it does this applies. No snake oil here.
I use cast brass machined screws to secure the transducers in certain bass columns I build with "Storm nuts", "I think that what some call them".
On the inside of the cabinet which are stainless steel with the (teeth), biting into the cabinets wood. I use fairly large screws and they are torqued to spec. so that the threads are not damaged.
If anyone really wants but cannot find that study I talked about above? And would like more info. I do have it here in hard-cover, book form. "Somewhere". I would just have to dig it out.
Tell me where he asked for measurements as this is what I read as all that came before it was pretty boring and starting to become a pie fight, so I skimmed right to the last page. All I did was to let the naysayers know that what you're trying has long been heard and that you're not some crackpot, but maybe I was wrong. Pretty plain to see.

All the best,
Nonoise

nonoise,
I did indeed misunderstand your response upon carefully reading it again, and I do owe you an apology. I am sorry, and I do apologize to you.
