Audiophiles should learn from people who created audio

The roger-russell article is not relevant till science will be able to provide accurate tests for measuring:
Brightness
Seperation between instruments
Quality of treble and bass
Soundstage quality
Level of details
Level of transparency 
Level of refinement 

All the" scientific " tests are not relevant for cables because they didn’t found a reliable scientific tests for the human musical skills hearing.

Some naysayers will say that the waterfall graph covers the aforementioned categories but they would be wrong. That doesn't address those qualities that are easily distinguishable by ear but to them, readily rejected. 

All the best,

Agreed. I find waterfall graphs incredibly useful for dealing with my room acoustics. As I’ve taken more and more measurements, it had surprised me how variable they are. There are obviously way more similarities between each measurement than differences, but there are enough differences to let me know that any differences in sound due to cabling would get lost in the noise of in-room measurements. I suppose you could do hundreds of measurements before and hundreds after, then try to average them and create a before/after waterfall plot, but, unfortunately REW doesn’t generate waterfall plots from averaged measurements.
