Becker speaker/microphone box - shall i get rid of it?

My glider is equipped with a quite old Becker box. The microphone cable is in very bad conditions and i have a bunch of cables going back and forth from the panel to the box, which is fixed close to my right shoulder behind the seat. I'm wondering if this is really necessary, or if i should go for a much cleaner setup with just the microphone cables and the ptt cables starting from the radio and that's it. Is there any good reason to keep the Becker box, and refurbish all the connection cables?
Thanks for any advice.
