rushca01.......Burn-in is no different with Schiit components than it is with other electronic components. What constitutes burn-in is a period of time with components energized that allows the various electrical parts to create electron flow, while at the same time rising to and maintaining operating temperature. The burn-in period will vary from component to component, but the basic idea is to allow time for the various internal parts to settle in values that eventually eliminate minute shifts in the way a part works in a circuit. Temperature differential, electron flow, and molecular movement of the materials and chemicals used to fabricate parts gradually stabilize in a more finite way with time, temperature, and use. It is this stabilization process that audio enthusiasts call burn-in. Manufacturers use the burn-in process to weed out early failures that will usually happen within the first few hours of a component's life.
In the case of R2R multibit DACs like the Schiit Yggdrasil, the ladder DACs and the discreet filter stage needs time to rise to full operating temperature to ensure that the extremely close tolerance parts are operating within the proper specifications. Then there is burn-in on top of that, a period of time where all the various stages of the DAC reach a peak settling where no additional variation remains. Some say the Yggdrasil DAC can take from one month to three months of a continuous energized state to arrive at what is considered full burn-in.
Added to this topic are those who believe burn-in is a myth, that all audio electronics perform at their peak on day one with no appreciable difference from initial powering up to the end of its life cycle or internal parts failure. Burn-in, or break-in as some call it, is looked upon by those who do not embrace the notion as a perfect example of audiophile nonsense. I am not in this camp. I have personally experienced break-in of many audio components that have responded to hundreds of hours of break-in with a remarkably positive improvement of their sound.
This may not be a succinct summary, and others may be able to clarify the explanation better, but I hope this helps to answer your question.
