A scientific explanation of how a power cable changes the sound. Microphony is known but how does that pass through to the analogue side (does it actually?). What does it do to the components and how does that affect the sound.Vibration and skin effects are all well and good, was never seems to be explained is what effect that creates. Noise is mitigated. If there’s a concern about vibration, why are we spending 40k on amp boards and digital circuits that are bolted to something that vibrates for a living...
