Audiofeil is lucid as always, if not a little terse. His points are all well taken and fully understood. My bias and passions have been laid bare before the altar of the almighty. Still, my 46 + years as a musician, music lover and high end enthusiast have drawn me to certain products that I (and many others both professional and amateur)have found to be the "best of the best". My scientific background has compelled me to read many a white paper as well and geuss what?....MIT has been addressing the problems of audio signal transmissions via wire for a long time. They have the science to back it up and the following of many musicians, industry professionals and reviewers worldwide. All this means nothing however if the results were not phenomenal...and they are! As for the power conditioning, I speak from many trials and errors with other brands, albeit not all that exist. Still, nothing has ever made the improvements of my MIT Z HG without getting in the way of the music. The bottom line for me is that I don't feel anyone should go out and buy by recommendation...one should simply give these products a try and decide for oneself in ones own home.
