The Green New Deal is going to kill everybody? Now that's good science.
I leave things on if they're doing something. I turn them off if they're not. It's even better to unplug things, but that's often a pain in the butt.
So a DAC that needs to be on 24/7 or otherwise the sound quality is significantly worse? Er... Now granted, it's great even cold, but this is a significant design flaw. They could, I dunno, add some warm-up circuitry or something.
In the end, though, I'm not interested in a two-channel DAC nor one without integrated DSP. Give me 4+ channels and a DAC or give me death!
