once again, I don't PERSONALLY necessarily huy that power cabling is worthwhile area to fret about.
but all I AM saying is that reputable, smart, experienced, talented people tell me it's worth paying attention to and I am unwilling to just dismiss what they say out of hand because "the internets"
at the risk of rabbit holing:
it's bit like the '96k doesn't make a difference' arguments.
thats great on gearslutz.
in the actual record making world, all the high end guys I know (and I know them all) work at 96k of not 192.
but if you'd rather take advice from a bass trap shill, feel free.
won't bother me.
