Exactly Zavato.
Teoaudii, that is why good engineers design for stability and hence properly applied even with a complex load distortion can be much less (even or odd) with negative feedback than so called linear amplifiers which are only somewhat linear. All comes down to implementation.
Williewonka. 50 years and never once see a slimy deposit on wire and I have stripped a lot of wire. Sounds like Uber cheap offshore or some boutique brand that did not know what they were doing.
Felixa the op stated stranded 14 awg. Most definitely not skin effect classic or otherwise. Inductance would be a much bigger impact at 20khz.
