What exactly is happening during this "burn in" time with cables, amps etc etc? And no, this isn't a "bait" question, I'm really wondering.
I'll preface this by stating I'm certainly no expert regarding answering burn in questions, however, to my understanding it applies most to capacitors, so that they "form" correctly (or optimally). In the case of my speakers (Golden Ear T Ref), Sandy uses the term "heal" in the case of the crossovers, which include caps. Personally, I'm not a big believer in burn in of any kind when it comes to cables.
