Is there any danger in leaving a class D amp on unattended for ten days?

I recently obtained class D (Red Dragon monoblocks) amps.
I have left them on continuously for about a week, and they seem to be improving sonically with every day.  I am planning to be away for ten days starting next week. Is it unwise to leave them on unattended for this period?

My system is on all the time. Like markalarsen, the only time the system is off is if the power goes out.

I don't know about others out there in Audioland but when the power unexpectedly shuts down and then starts up (could be a second or could be much longer) it effects my tube gear and turns them on. I don't want my tube gear on when I'm not listening or at home.

How can you be sure an amplifier really does sound better when left on? Human sonic memory is not more than a few seconds, so you can only know if you compare two identical amplifiers, one left on for a while, and the other started from cold. To be honest, if there really is a difference (which in most cases I doubt), it would be a bad design.
Apart from the two disadvantages I already mentioned (fire risk and harm to the environment) there is of course another one: heat is the enemy of electronics. Leave your gear on and you will significantly reduce the life span of critical components.

no way to know for sure, no way to prove...just an impression from using the same gear for a bunch of years...I do a combination of on, standby, unplugged depending...though I am more inclined to leave the amp on during this Arctic blast, less so in summer...

While auditory memory is shorter than visual memory, to suggest that auditory memory lasts for just a few seconds is an oft-repeated claim by audio measurementalists such as yourself. Oddly, I've never seen it accompanied by any documentation. Do you have any to offer?

Nonsense. There is plenty of audio equipment - and other electronic components - that is rated for continuous duty. My ARC SP-11 preamp was left on essentially continuously for decades without issues. I sold it to a friend a few years ago ... it’s still running like a charm! And that’s a tube-based component.
