2 conductors vs 3


My Marantz SR7015 uses a 2 Conductor 16 AWG power cord.
What benefits might come from an aftermarket 3 Conductor cable?
Is there any benefit from a larger gauge conductor even without use of the ground conductor?

Does a third unused conductor bring any negative issues?

There are 2 benefits to using a 3 conductor IEC cable instead

  1. Better grip thanks to the ground pin in the IEC socket
  2. Some grounded power cables are also shielded, but most are not.

Of course, you only get benefit #1 if your IEC socket has a ground. For this reason I upgraded my Luxman’s socket. The ground is not internally connected but it increases the grip strength by about a third.

I also use shielded power cables to reduce the chance of picking up noise from all the networking and streaming gear I have behind the rack.

I wouldn’t hesitate for a second to replace that cheapo 2 conductor 16ga cable with a good, doesn’t have to be expensive, 3 wire after market power cord. I would probably look at, minimum, a 12ga conductor power cord. Try before you buy if possible... You will hear a difference for the better!

As for the ground wire in the cord. The IEC inlet connector on the back of the Marantz receiver does not have a ground blade. Two blade only.
