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 can't speak to the sonic value of adding a PC to the 3020D. That said, there is a new 1.5 M Pangea AC 14 for sale on Ebay for $40.

Yes, the AC-9s are recommended for amplifiers. However a 2M length of AC-9 would weigh about as as much as the 3020D. I think the weight and stiffness would be difficult to manage in this case. 
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!
