To better audio performance.
Nothing more specific? I think a headphone cable would have to carry a pretty insane amount of current for it to become hot enough to show an audible difference in Johnson-Nyquist noise. The headphones would probably melt long before you reach that point. And if they didn't, the SPL would kill you
But yeah, I get that it would be nice to put a nail in that coffin. IMO there's just waaay too many myths on the same level as silver cables. If Amir was to test all of them, he'd be doing nothing but debunking cable risers and other nonsense from now till hell freezes over.
