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 - but I praise a lot the fluidity, energy, soundstage and layering of music. In stereo sound reproduction, these aspects are also conveyed manipulating the spectral characteristics of music - it is how great sound engineers can recreate a 3D illusion in our room with sound coming from two single physical sources. Systems will always be a balance of compromises - and here fortunately we become the accused, the jury and the judge, at best others are allowed to play the lawyers ...
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.
