Here is my experience with the Nordost cable line:
There is improvement as you move up the line.
The power cables make the most difference, followed by interconnect cables, with the speaker cables making a noticeable, but the lease difference.
I made each upgrade after careful comparison to my existing cable. One of the main differences I noticed moving up the Nordost line was a reduction in background noise resulting in a blacker background, and a bigger sound stage.
My system is posted here so you can look at it if you like.
I am currently using V2 speaker cable, V2 power cable, and Tyr 2 interconncts.
