RE: warm-up What do we think the science is behind needing a warm up of a month (from a power up)? I can't get my head around what would require that every time. A break in period, yes, i get. Hitting an temp of all components makes sense too - but that wouldn't take a month (let alone days.) I don't doubt that something is happening. It is pretty universal that people say the yggd sounds much better after it has been on (post a power up) after a very long re-warm up. Also, is this effect reset on a power loss or is a cool down? ie, well a fast power loss reset the timer? But i'm already really enjoying it. It was a big jump up from my old dacs (crappy? Oppo HA-1 / Audiolab M-DAC/ Fostex HP-A8 / Dragonfly Red) also my desktop speakers are much better too. From PSB Imagine mini to Elac BS403.
