Power cord for Aurender N20?

My experience with the N20….  I was advised that it will be sensitive to the power cord used and I opted for the more expensive cable in my system. I was pleased with the results. But since we are in the hobby we’re always looking for more. So I did an experiment and swapped the better cable from the N20 and put it into my DAC. The lesser cable into the N20 degraded the sound. It wasn’t a small thing because my wife asked me what I did to break the system and was not happy. Can’t make this stuff up. 

I use Puritan Audio Ultimate XX Power Cables in all my equipment, including my N20. I have been very happy with them and the Puritan Power conditioner. 

I don't own an N20, but I have a great streamer with an excellent power supply, the Innuos Pulsar. I recently had a chance to demo the Shunyata Alpha-X NR and the Snake River Audio Takshaka power cables in my home system, using the lending library at the Cable Company. Both of these cables should be available for less than $2500 new with appropriate discounts (and even less money if buying used). I compared these two cables to my regular power cords (Shunyata Theta and Delta, as well as Cardas Clear) when used on my streamer, DAC, preamp, and Atma-Sphere GaNET monoblock amps. I found that cable changes were noticeable throughout the streaming system, but were more apparent on the streamer and DAC than on the amps and preamp.

Comparing the Alpha-X and Takshaka cables on my streamer, the Alpha-X sounded significantly better. I was particularly impressed by its balance of high-frequency air, mid-range sweetness, and low-end impact. This was achieved with realistic body and tone, without any listening fatigue. It's possible that the higher priced Shunyata cables would sound even better, but I wasn't willing to make that large a financial commitment to power cables.

I haven't heard the Alpha-X on an N20, but you might want to see if you can demo one in your own system. I did notice that the reviewer who wrote the positive TAS review of the N20 (from a few years back) was using a range of Shunyata cables in his system when he produced that glowing review. Good luck with your power cable search.

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.
