I see all these tweak threads. They always lead into a measurement vs hearing debate. Has anyone ever proven they can hear something that can't be measured. If someone can prove they can hear something that can't be measured it would go a long way toward justifying some things can't be measured. I mean with all the different tweaks, cables, Ic's,treatments etc that people claim make huge differences, Has anyone ever proven they can hear what can't be measured. Thousands of threads on the internet about this stuff but I have never seen just one person prove it. I love to read this stuff but from a logical standpoint it doesn't make sense. Why does anyone believe this stuff without anyone proveing anything?
