Power cord for Aurender N20?

Thank you all. This is very helpful. 
Rick you mentioned your positive experience with cable swaps, but failed to mention which company and model you ended up with. 
sdl4. Yes I have heard good things about the Shunyata power cords on the N20. 

I am a fan of Acoustic Zen power cords, some of the best IMO.. all my equipment has Krakatoa cords, and my main power conditioner that feeds everything has a Gargantua... BUT on my Aurender N150 I used a pretty expensive Acoustic Revive cord, it was about $1200 ten years ago before the hyperinflation and it sounds fantastic in that spot, not sure what the model number is but they make awesome stuff that is really expensive and kinda hard to get in the States.

Iceage Power Cable. Their best one,  the OFC Series,  worked great.   Noticed an immediate improvement in sound quality with my N20.

On my amplifiers and pre amp I have found some subtle differences when using well built and shielded power cords, say Cardas Clear. Others may disagree but most high end connectors have very subtle differences. Almost any power cord is a real improvement over what’s bundled with the packaging. Amps/Pre/Speakers are most important and deserve the best followed by the rest if there’s a resources allocation need. 

However all power cords are coming out of power conditioners and that’s key.
