....and the rest of the confused crowd,
By definition, empirical measurements require the use of a commonly accepted scale of some weight or measure. Therefore, no listening test can be empirical. Without some empirical scale, the "listening measurement" (a true oxy-moron) is purely subjective. It could only be objective if there were such a thing as a standardized ear and perception and all conceivable variations controlled for. You people aren't even doing a basic multi-variant analysis, which is the closest you could possibly come to a useful, scientific analysis.
I'll also take note of the fact nobody has of yet questioned my assertion that susceptibility to the influence of a fuse is a failing of the power supply.
Carry on with your mischaracterizations, conflating of terms, and misunderstandings....
