No, I never turn off the monoblocks. Being class D, they produce very little heat, and being NCore, they didn't pop. But I do unplug the headphones after each use, in case there is a surge in the line.And do you have to unplug your headphones every time you turn on and off the monoblocks to avoid the pop on and off noises?
I can see other say its mandatory for class AB amps, not sure if it is for class D as well.
For an added lair of protection, you can get an attenuation box like the HE adapter. This would give you a little more headroom out of your pre-amp / DAC.
