The most egregious parts are under the "Dielectric-Bias System", which claims: "All insulation slows down the signal on the conductor inside" and "when insulation is unbiased, it slows down parts of the signal differently, a big problem for very time-sensitive multi-octave audio".
Ignoring the offensively ignorant implication that audio data is transmitted in analogue form, is there any truth to their assertion?
