tone arm wire modification mayware 4, on lenco75

I would like to use the best DIY wire conversion to my tone arm ( a mayware 4 ) it has original cable leading to preamp, of cause . some people love to use a silver wire ?
which one , from a medical supplier? or other, high purity right?
I am a DIY'er and can solder reasonably well .
The mayware is light and elegant well balance sound I think but have not compared it to many other arms on my system .
What possibility's do I have for effects , to bring weight or depth to the sound ?
