Has anyone tried Brass cartridge mounting screws?

From Reference 3A's website

" Driver frames are fastened with softer metal brass screws to avoid resonance noise potentially generated by similarly hard metals" 

Perhaps that theory holds true for cartridge bolts.

Are you having an issue with the brass threads stripping or do you not like the sound of brass bolts?
