Touching on the subject of burn in, this cable is pretty benign from the get go but will intensify significantly over a few days left on repeat. Generally speaking, most listeners will be wowed from cold however those with Intona Ultimates as their reference will need to give it a bit of time. I guess that says as much about the capabilities of the Intona as it does mine!
I used to wish for gear that didn't require burn-in, but eventually just adopted a stance that everything new I add to my system requires some amount of burn in, and so I just give it time. This makes it a non-issue, and also forces me to avoid jumping to hasty conclusions. Win-win!
