I would not say that either PAD or Kubala Sosna are neutral sounding, that is why so many love them, they are warmer and more musical sounding. Neutral is a very gray area, it means many things to many different people. Many will recommend Nordost as the most neutral cable brand, but I think that Nordost highlights the high frequencies, which is not neutral IMHO. Stealth Audio, Tara Labs, and the Kimber Select silver cables are also considered by many to be neutral, or more revealing sonically.
