A separate ground wire is not always needed. Try it with or without and go with whichever results in less (or hopefully no) hum.
tonearm cable vs regular IC + ground wire
This may be a stupid question, or not.
If running between RCA connections on both ends (turntable and phono stage), is there any benefit to a dedicated tonearm cable, with the integral groundwire, or can you just run your IC of choice and hook up some generic wire for the ground?
