I also sold many Nordost cables and I also know exactly how to use and what the properties are. I was the first one who bought the Valhall loudspeakercable in my country. I also did a lot of testing with the the rest of the Valhalla cables in mu system. Now I also use Valhalla powercables for a part in my system. But When you use only Valhalla cables you will miss important parts in you system. The most important part what is missing, is individual focus. There are cables who cab do this so much better. But Valhalla is the only cable who can let you hear the highest resolution. Use a live recording and you know what other cables miss. I use a Purist Audio PC on mu power amp. It gives me more information in the lowest freq, yes a lot more than a Valhalla van. Also it gives more depth information and has a richer mid. So when you want to have the sound you are looking for, the only way is to use different properties of different brands. I wanted to have a sound what has a lot of depth info, high resolution, involvement in the mid freq, a very good individual focus, control and speed in the low freq, the right proportion of a voice and instrument. A Purist is capable of getting lower in the low freq. than other cables can. I wanted a system who has all these things toghether, and yes it is possible. And now I have a sound to die for. I am sucked in the music and I can touch the people who are playing in front of me. It feels if they are standing in my room. And that gives me a feeling of live music. Just by using different properties of different brands.
