I agree the lower lines of K-S are a bit dark and less resolving on the high end. I initially tried a full loom of Emotion power cables and did not like them as much as the Au24SX. But not true at all of the Elation and Realization lines. These are very resolving and balanced, full spectrum and natural. No bloat on the lows and now glare on the highs.
And I agree the Acoustic Zen cables are nice and a value. I recently purchased a used pair of Hologram 2 speaker cables for my vacation home. They are really nice, and a really good deal used. but they are not K-S Realization or Elation, to me. Same with their interconnects.
My system is very resolving. I have so far not liked cables with silver, as they can be a bit tilted towards the top. But, I have not tried high end cables with silver.
