Don't bother unless it starts humming. As you climb up the food chain in this crazy hobby, you will find out that different wires sound different ways, however.
Turntable interconnect
I do not know much about analog I am currently using an interconnect without a ground. There is no hum. Should I spend the money and get a regular phono cable with a ground. Have a VPI Classic and Nova Phonomena phonostage. Any advice greatly appreciated.
