With modern amps and DACs there is no benefit to leaving them on all the time. Especially amps like the c3050le, which is class D. There’s no benefit to modern solid state amps being “warm” or on at all times. In some older gear on/off cycles could shorten the lifespan of some capacitors, but modern components don’t wear out like that. DACs being always on has no benefit either. They’re generally made of solid state components which don’t need to charge or warm. And even if they did, this would happen within seconds if not milliseconds.
