Should I replace hardware?

[Shareef]

Hi everyone,
I have a bass (A Yamaha RBX375 to be precise) which i abosultely adore. I have tried out many more expensive basses and all but a few still had me preferring my old Yammy.
Seeing as it is a mid-range instrument, i'm planning on tweaking it out a bit to make it more professional-grade. I have already had it set up, intstalled straplocks and i frequently replace my strings with my favourite brand (Ernie Ball). I have decided to replace the preamp at some point as the stock one can be a bit buzzy.
What I was wondering is whether swapping the hardware will make any difference? I have no tuning problems but will replacing the tuners/bridge make it a better instrument in any way or am I just being stupid?

If it stays in tune...the tuners and bridge won't make that much of a difference in tone, yes there is the more mass equals better tone club...but I would focus on things like a nice nut, maybe bone and a proper setup like you said it has.

nothing stupid about thinking about how to improve your tone and setup!!
