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

Millercarbon,
Yes, all small things matter, and some matter a lot. I am now going to experiment with gasket material. I looked up the material that you are using...ouch! Pretty expensive.
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.
Hi Mapman,
That is the reason that I was so surprised at the difference. I tighten my drivers on a regular basis, and had just done so 2 weeks ago, so they were tight before I changed to the brass.
Have you measured the speakers before and after to make sure its not your imagination? Don't be so silly.
+1 this is just "fuser" snake oil stuff from the same voodooists, SR are probably about to release cryo'd brass fixing screws for $500 a set.

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.
