The PK-10 powercabels are a lot better than the powercables in the lower price ranges of Nordost. I know it, I sold them for over 9 years of time.
The limitation of the Nordost is that they are incomplete. Even the Nordost Valhalla powercables ( I owned them and sold many of them) are incomplete.
So what is incomplete? Sound is created by about 8-9 different parts you judge sound for. Stage depth has always been a week point of Nordost and still is.
The other limitation is individual focus of instruments and voices. In real voices and instruments are small and direct. Nordost is not good in creating a very small and direct focus of instruments and voices like other cables can. PK-10 is superior in this part compared to any Nordost powercable.
Each brand owns his own d.n.a. in sound and how the stage is being build. I know exactely the properties of Nordost. I have done hundreds of tests with them in the past.
That is why you cannot use a brand blind in a set. Because you need to be ware of the properties.
In the 9 years I sold Nordost I often combined it with Kimber interconnects to make the overall sound complete.
Nordost power, interconnect and loudspeaker cables are togheter incomplete.
When you change the Nordost interconnect by a Kimber interconnect you add different properties.
What did it change compared to a whole set of Nordost?
It made te stage deeper and wider, the individual focus became a lot shaper, intimate and palpable. And the mid freq became richer and more musical involving.
That is why you need to understand the properties before you can buy any brand. This will never give good results.
