RS A1 Labs rewire

I once read a thread here whereby someone had done a rewire on their
RS A1 Labs stock tone arm resulting in an improved sound. I have had this arm
for several years and replaced the stock wire with same from the factory. I have tried but have never found a wire light enough to replace it with for an upgrade
in sound . I also understand that they went from cartridge leads straight to
the pre amp inputs. I would appreciate it if anyone can shed some light on this.

Thanks
