The most detailed speaker cable??

The Nordost and kimber 4TC always seemed on the bright side in my system. I am currently using the Analysis Plus silver oval, and I can assure you that they are not even close to being bright. I also have the AP oval nine's, and believe it or not, they are brighter sounding than the silvers.I think it would be helpful if you posted your system, as I cannot imagine it sounding mellow with the Kimber or Nordost.

Nordost Blue Heaven
Signal Cable Silver Resolution

Silver Audio is known to make excellent speaker cables, and I believe there's a set for sale on a'gon right now.

Good luck.
