Question? If Breaking In a Audio Device, it is expected that at some point the device is going to settle, maybe become coherent in the way it manages frequency.
Settlement and coherence are typically seen as a positive and attractive to have available.
Does not just using the Audio Device create this without the use of a particular source material.
Claims a breaking in device was a better outcome than usual music used is a biggy to take on board.
Now a long term in use device that is optimised in its function. If that was claimed to find a little extra resulting from a source material in use, that might be more alluring.
