Has anyone tried Brass cartridge mounting screws?

 I just bought a set of screws off ebay from the UK.I notice quite a difference in midrange and bass but I had to put the counter weight back further on the tone arm to compensate for the extra weight so I really don't know if it was the screws.Anyway whatever the case my rig sounds better for less than 20 bucks.

too funny

Maybe you have to check your arm effective mass and cartridge compliance first (you could check with HiFi test record).

Adding mass is not always necessary (or act like improvement), but sometimes you just need higher mass for low compliance cartridges if the arm is too light.

I think you’re dealing with effective mass, or you just screwed your cartridge better when you changed the screws

I don’t believe in that esoteric BS and snake oil that material of the screws can improve the sound, they are just fixing your cartridge to the headshell.

The benefit of the screws i posted above is that mounting process getting much easier, they are bigger and can be tightened by fingers first (then with a tool), and they add mass a bit to change tonearm's effective mass a bit (when needed). 

  Chakster I think you are right.When I loosed the stainless screws they were not that tight.The brass screws I got look like same style as Sound Smiths,maybe smaller.

If they hold the cartridge firmly in place you're done, nothing to talk about

When you are trying to lose mass screws are more critical. The difference between aluminum and stainless steel or brass screw is significant. In trying to add mass the difference between stainless steel and brass screw does not amount to much. You have to do something more substantial like head shell weights.
