It seems pretty clear that the cable break in phenomenon is part of the whole cable controvery that has been going on these 35 years or so. Once one breaks away from the basic ideas that all cables sound the same, that higher purity conductors are no different than lower purity ones, that the length of cables doesn't influence the sound, that the dielectric material doesn't change the sound, that thicker conductors are necessarily better than thinner ones, etc. then one can experiment with breaking in cables, how long it takes to break in cables, the best methods for breaking in cables and so forth. A great many cable manufactures have obviously concluded that cryogenics is required to be competitive and quite a few manufacturers offer free Burn In of cables for customers on new fangled burn in devices such as the AudioDharma Cable Cooker. And Break In tracks on Test CDs have been available for at least 20 years. How far can one go with all of this? That is the burning question.
