Tplavas, Thanks for your parting shot. Convoluted logic reins, and you mention "reasoned debate"?
DBT does not prove that no difference exists, only that the difference (if any) is beyond the sensitivity of DBT testing". Huh?
Again, when I hear about so many epiphany's, such as your cryo'd cord that "even I'd be able to hear a difference with" (and I'm the mocker?), which drop jaws, lift veils, and makes life worth living, then find convoluted ways to obfuscate the fact that often the only way someone could identify the latest world beater on a statistically relevent basis was when it had a 1,000 watt neon arrow blinking above it, the contention becomes rather thin.
It's not "beyond the sensitivity of DBT testing", it's beyond the sensitivity of the subject's ears to differentiate the difference, meaning the amount of perceived difference is not significant enough for someone to recognize at better than a guess level.
Try another parting shot.
