All new Regas come with a cable attached.
If the arm was "upgraded" rewired with a DIN plug you may use any phono cable, DIN to RCA connection. The Incognito Cable upgrade in one continuous cable from clips to RCAs and is very good. I have done 3 RB300s I have owned.
I now own a RB700 on a P5 and would not change a thing on it.
