And no, cables do not need to be burned in. Save 100 hours of electricity or more!
There is nothing mechanical about a cable.
A new car requires burn in, a new amplifier, CD player,
Or DAC also does. But not cables. Cable temperature only rises while in use; so at room temperature they return to original factory temp - which is close to room temperature plus whatever the cable insulation jacket adds or subtracts. The process of cable burn in would have to be a structural change in the conductor that wasn’t already present when the speaker cables or interconnects were made. No magical fairy dust can cause this to happen...unless of course your cables oxidize after being exposed to too much air over a sustained period of time. I guess one could call that: cable burn out! :)
And there are companies who make cables and burn them in for you!
Meaning it simply sits in the warehouse for a few extra days and in that time they can fulfill more orders, while delaying delivery of your cables.
All of what I'm telling you is not rocket science OP, but I speak the truth. The folks who disagree with me are clearly Harvard educated, advanced electrical engineers, and have IQs that surpass the folks at NASA. That's why they know so much lol
