Audioquest NRG Z3 power cord

Order 1m extra just to account for the long bends you have to make with these stiff cords.

About sound quality: yet, improvement over stock cables. But I am not raving, again making the point that these power lines and conditioners are really subject to your local neighbourhood (I have a dedicated line, quite new house and the street itself is maybe 10y old).

Yes, You need to order extra 1 meter.

Improvements also depends upon speakers power requirements in addition to the quality of your input line. I do have a dedicated 20amp line. Thats the first thing to do if it's an option. The enteq meter shows quite a bit of noise on my dedicated line as well.

High Current outlets are not typically filtered (Although Shunyata Denali V2 has removed that restriction).
Niagara's High Current outlets show significant amount of noise on enteq meter, but the dynamics have increased for me. So yes, the improvements are system dependent. For me, they were significant with Mansoon and Niagara 1200. YMMV.

I would love to try Shunyata Denali V2, but they have discontinued the tower model for V2 in US and I have no rac space.
