Why?  DACs burn hardly any power so just leave it on 24/7 if turning it off is too much of a burden.  First-world problems.  Yeesh. 
Schitt recommends you leave theirs on all the time, have to reach around back to turn them off. Enjoy the music
I was not worried about power! some dac like bryston have a standby mode ! it was just a question, why do you have second world problems yeesh PS  audio gd runs class A on power supply HOT if you do not know
