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

Hello,
One of the reasons manufacturers hate to use brass screws Is they are hard to keep perfect and scratch free. They have to be hand tightened which makes it difficult to torque with a specific amount of weight. Even on an expensive speakers it is something that could cause problems. Also you probably need a revealing system to hear the difference. Last is it costs more. Maybe not a lot but it adds up. I will bet you it might only cost about $20 to try it. What’s the harm. We all spend thousands of dollars on our hobby what is $20 more. Also, sometimes people ask how did the electronic measurements look or differ. Do you know how many speaker manufacturers have a perfect measurement but the prototype speaker sounds bad. A lot! I think we should try it and post our results on this thread. Maybe we can get the screws from Ace Hardware. They carry a ton of specialized harware. If they don’t work return them. Cover the screw driver head with tape so you don’t mar them. If they do work. Good for us!
Hello,
How about this test. As long as it does not void your warranty replace the screws on one speaker. We all know when something is different with our system. If it sounds the same then it did not help your system. If it sounds off then there is a possibility it could sound better. Replace the screws on the second speakers and give it a listen for a few days. Make sure the screws are the exact same thread, length, diameter, and head size. 
It is really amazing how heated this discussion got. I wonder if this happened when the first person changed out their power cable to something different? Maybe even more basic when Mr Lee of Monster decided to upgrade speaker wires. Is anyone using lamp cord anymore?
