Indeed. How many audio amps that you know of faithfully reproduce and
send those kinds of frequencies to loudspeakers? I haven't seen the
issue of braid quantitatively addressed in rebuttal yet either and
the differences between conductor types that I observed at somewhere
around 140kHz (the test frequency from memory) was stark to say the
least.
