After 600 hours of burn on on the cable I got, and FINALLY! No more veil!Finally, a big food fight on this thread that's NOT about the V-Word!!
No really. the Yggy likely needs to be on for 4-8 hours to warm up, but after that, it should be good to go. The Schiit line of multibit DACs does seem to work better when they are properly warmed up. There might even be a scientific reason for that.
headphone burnin, for some headphones, can be very real. I was at a meet with a new Ether C and a burned in one. Everyone could easily tell the difference in a blind test. a year later and no one could tell the difference. That was one headphone that seems to benefit greatly from burn in. Many do not change it all. I would venture that most headphones don't change that radically, maybe 1 or 2 db at certain frequencies. It certainly possible a headphone that was sitting virtually unused for years might change a bit after use. Maybe it got a little dried out and using it stretched things back into shape.
Some people believe there is value in burning in cables. There doesn't appear to be scientific evidence of it helping, either measurable or ABX testing. That doesn't mean it doesn't help, it just means we need better ways to measure. Its possible the Yggy sounds different after the internal or external wires are "burned in". The likelihood this is true is very very small based on science, but it's not 0.
Ponder this: Is there a veil if you are Vail, Co?
