DAC break-in question

OK, so follow on question… do each of the inputs & outputs need to be burned in? IE: new pre… separate burn in required for phono line in, DAC in & HT in? Separate burn in for output to amp & headphones? Same question for a DAC, streamer in, CD in. How about each filter? I think the answer is yes, except perhaps the filters… but maybe even them. And then for how long? I don’t think my CD portion of my system will ever be burned in. 

Someone needs to explain the science behind electronic components needing to be “broken in.” I’m not denying that the phenomenon exists, I just don’t understand the science. 

There is some science and physics behind the break-in of electronics, but it has been taken way too far by people not understanding how minor it is and the reality. You do not need to break-in a component before listening, that's silly. Just plug the damn thing in and enjoy it. You must have the full circuit complete to break-in anything in the system as the circuit needs to be complete. Stop overthinking this, just play it and it will break-in with normal use. Don't expect some magical change.

I agree. In my experience if I hated how a cable or a component sounded right out of the gate no amount of break in could help. 

I am a true believer in “break in”. And you’re going to love that DAC! I had that in my second system and was blown away at the jump in performance when adding this to my system. What a great little DAC. Nothing comes close in that price range and even doubling the price nothing touches it imho. Enjoy!
