Anyone Upgrade NAD D 3020 Power Cable?


Wondering if this is a worthwhile upgrade considering cost of NAD. If you upgraded the power cord what did you get and what improvement did you hear?

Thanks in advance for your responses.

I should have added that the AC-14 I mentioned is being sold by Audio Advisor.
@mesch you are right the D3020 is very light so a heavy cord won't work

@mesch @elizabeth the PC connector is a ICE  C5 so I would need an adapter adding another $25 to the cost. I think I will pass on the PC upgrade, especially not knowing if there would be any benefit.

Thanks to all who responded! 
Sorry I forgot the power connector was C5. I had the 3020D in my possession for about a month when it first came out. Should have remembered. I believe Pangea only terminates with C7 and C13 types. NAD does ship there budget amps with some pretty low grade cords, 18ga I have seen.
