Francisco and David,
Everyone has their own interpretation and meaning of descriptors like "neutral". The better term for the Ching Cheng is "natural", that is, it conveys the timbre and tonality of instruments in a manner that sounds as one would expect from the real instrument. This is totally subjective of course.

Thanks for your comments, Marty. Although timbre and tonality of instruments are an important aspect of sound reproduction, there is a lot more in sound quality that I consider equally relevant. Perhaps I am not a golden ear listener - I can't evaluate timbre and tonality of instruments from the cellphone Youtube videos
IMHO the CC's strip some parts of the music in order to enhance others, as all other cables or equipment. Considering your speakers have high-efficiency and have a nice impedance curve I can't see any technical reason why they should electrically limit bass transients with your current amplifiers - again IMHO, they are affecting the sound in another way that subjectively suggests it. But yes, most power issues are still voodoo in stereo.
My opinion on "natural" has been slowly evolving to the point I now consider it as Babel Tower word - it mainly spreads confusion in debates, precluding any proper analysis.
