Esoteric K-03 / K-01 Leave Power On ?

Digital should never be turned on it takes one to two days for the digital to sound as good as it normally would.

The act of turning on and off components is much more damaging, and the K01/KO3 will use such a small amount of power you wound't notice any savings. 

Just leave it fully powered on and be happy you are getting the best sound from it.

Leaving a component always on...will ultimately lead to capacitors drying out. Since this fact is always overlooked by manufacturer’s who recommend a component to be always on ( or sitting idle, but connected to power), I thought it would be helpful to bring it to our attention. I know this, having replaced caps in several components that one has no choice to either leave on ( or in sleep mode)...or unplug from the wall. While we may be talking of several years without this issue, the issue will occur...it’s just a matter of time!
