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

This reminded me I have not checked the wing nuts on my Ohm Walsh driver boards in awhile. They were still pretty tight but one or two had a slight give. Now they are tight for sure and I think I hear a difference.

Or do I? I have a pretty active imagination sometimes.

I can say for sure it sounds darn good right now which is usually the case.

Well brass screws are not expensive so if someone thinks they are worth it not a big deal.

If Uber expensive audiophile brass screws from Synergistic or others suddenly start popping up it would look very suspicious.

The drivers need to be mounted securely for sure. Loose screws/drivers not firmly mounted will negatively affect exactly the things the op mentioned. As will defective gaskets. Most screws will need tightening from time to time in that the vibrations from drivers naturally tend to loosen them over time. So don’t forget to make sure drivers are tightly attached from time to time. This surely will have a negative effect and I would expect to a much greater degree than the metal used in properly applied screws could.
