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

My 3116 chip amp hasn't been off since I set the system up, but it's probably more prudent to turn everything off if you're going to be away.

I would not leave electronics ’on’ unattended without power condtioning. Who knows what might happen if the power goes out. High frequecy noise spikes could damage your system becaue it is digital not unlike a computer. A legacy power amp would be less susceptible. It is not worth the risk of component failure burning your place to the ground which could happen
   My recommendation? Turn on the system 15 minutes before listening and have a cup of tea or coffee. Relax.

Whenever we go on vacation I turn my audio equipment "off", and since my system has a 1500 VA APC battery backup/UPS between it and my wall outlet, I don't "unplug" the units, as I once had a bad experience with the firmware in my preamp getting corrupted (source of that problem unknown), and all my equipment together consumes less than 10 watts connected, but turned "off".
