Markem can surely give a better explanation than I but primarily
mechanical resonances. Obviously these need to be controlled in-band but
my understanding is that out of band resonances can have an effect in-band
Only becomes noticeable at /high/ frequencies. There is a formula but not
suitable for a plain-test news post.
With 13A copper mains cable at frequencies below 13kHz the skin depth is
greater than the cable radius. At 20kHz the skin depth is 0.47mm and the
conductor radius radius is 0.6. The conductor resistance increase from
152mOhm to 160mOhm per meter which will have no appreciable consequences.
Sure it will, particularly, as with most "brand name" audio cabling,
when gauge and length of run are taken into consideration and matched to
the components ... something not necessarily taken into account with
cheaper speaker wire.
That is an inarguable, scientific fact.
Only extreme arrogance would automatically assume that since they can't
hear the difference, others can't.

One odd exception however is my dust collector and my stationary planer.
Neither are bad by them selves just running and not working but both
together seems to triple the noise at the planer.
What are you running, Max? Or did you just get some clothespins and
playing cards set up in the intake to stroke the impeller for that
My Griz 1029 is a quiet, strong sucker; a real sweetheart.
Energy and persistence alter all things.
