@samureyex ”….anything with a wire can require burn-in…..”
Ears to brain requires an array of wires of sorts. I suppose this supports those with theories that the brain (not the equipment) adjusts. That the brain is the true burn-in culprit, which tricks us into believing (over time) that the components in our systems are changing the perceived performance.
l think if people want to hear a difference, they may well listen in more detail and think they are hearing things they never noticed before. Our Hi-Fi systems are invariably courtesans, which hoodwink us into believing, what we want to believe.
