Nothing in his assessement that cannot be contributed to the 'psycho-acoustic' phenomenon. His terms are typially vague, are they not.
Of course a silver cable will 'sound' different than a copper wire. So what. For me the question is what replicates what is recoreded on the source material the more accurately. No progress will be made with wire, tweaks, or top end gear, until the speakers/setup is maximised for the environment, and a distortion free amp is powering them.
Of course then, one is so drawn into the music there is little incentive to play around with the more subtle affects for various combinations of sonic characteristics of other components and tweaks.
The 3 primary issues for real estate is, location, location, and location. For 'true to the original' playback in audio, it is, speakers, setup, and a distortion free amp.
Then furnish the rooms, add a pool, and landscape the grounds.
But whether the style is Tutor, Modern, or Mediteranian, will not change the location, if you see what I mean.
