You´ve all forgotten the Voodoo factor here!
When hi-frequency sound vibrates together with lower frequency sounds they together produce sounds, and audible sounds too. That´s why we respond to higher frequencies than normal hearing range...
Sampling in 192KHz is way better than 96KHz, just because of the Voodoo factor. I would gladly take a blind test anytime, and I would pass. It´s easy. Try to picture it like this, like the sky would open, like the roof went away, and there was more air and easier to breathe. Like moving from a 3D world to a 5D world.
I look forward to 384KHz too
