Here's how you figure it out:
1) what connectors are on there now?
Try to establish a baseline - look here and on Audioasylum to see how people characterize their sound
2) what about them are you trying/hoping to improve
Look up some different mfgrs and see how people characterize the sound - in a few cases like Oyaide there are very specific descriptions of the sound based on the plating materials
3) what did you spend for the cables
Is it worth investing in them or starting fresh
4) how much do you want to spend to improve them
If you have a budget this has the (not so) pleasant effect of narrowing your search. Plese understand that there is generally no resale value for a DIY termination. If you are unhappy with the results you can probably sell the connectors for 35-40% of parts cost
5) how will you terminate them (do you have soldering skills or are you looking for a screw based solution)
Certain brands are better suited to those with no soldering skills - for example Furutech
As a sweeping generalization something in the Oyaide or the Furutech line will provide a SOTA solution
