Twl has it exactly right, although maybe the way he said it confused some people. The lack of a scientific measurement which correlates exactly with some particular "thing" that you can hear, does not mean that the "thing" does not exist. All it means is that science hasn't figured out how to measure it yet. The whole world is this way, not just audio, and so it always surprises me that people expect scientific perfection out of audio when, for example, medicine is still in the dark ages (in relative terms, at least).
Opinions on this "white paper"
I read InnerSounds white paper on cables and it sounded very logical. Any comments:
white paper
go to "Accessories"
then click on picture I/c's and cable
click on "white paper"
Briefly:
Co-axial speaker cable has lowest inductance and capacitance since the amp "sees" both + and - in the same place so it is the best.
All Well Designed interconnects sound the same and there is no such thing and time smear, etc. in I/C's.
