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

The cited study doesn’t seem to correlate with the real world experience of listening to either recorded music via an audio system or listening to live performers. If our aura recollection was only seconds we’d have no meaningful memory of the event. This would render listening to music a futile event which it certainly is not. Auditioning audio product would be useless as we’d have no recall of what we had just listen to.

I don’t see how one can extrapolate from this study that humans do not retain good aural memories of listening sessions. Why then have good sounding sources,amplifiers or speakers if our recollection of how they performed is so fleeting? IMO this study doesn’t relate to actual music listening experiences of the legion of music lovers. The study focus was dealing short intervals of comparing different or similar tones/pitch with a brief interval. No one I know of even remotely listens to music under these type of restrictions or conditions.

I totally concur. To think that audio memory is momentarily fleeting flies in the face of massive experiential evidence to the contrary.
Why do we even give any credence to this theoretical construct?

We have a much longer memory of what we enjoyed and what we didn’t. Interesting article but tangential to selecting audio components 

Regarding the original question, a point which the post by Itsjustme alluded to but which has otherwise not been mentioned in the discussion is the possibility that failure of a part in the amp could conceivably result in effects such as very loud oscillations, or large DC voltages in the amp's output, or some other such possibility that can destroy the speaker it is connected to if not caught promptly. Especially in a case like this given that the 5 amp mains fuse of the amp in question (Red Dragon M500 monoblocks) will not blow unless the amp is drawing upwards of 600 watts of AC, while the amp is capable of putting hundreds of watts into the speaker without that happening.

And I certainly would not count on the designer (a)having foreseen every conceivable failure mode that might damage a speaker, and (b)having addressed all such possibilities in the design.

Finally, the fact that the amps are fairly new adds to those concerns, as failure of an electronic component typically has the greatest likelihood of occurring when the component is either very new or very old.

On another note, a happy and healthy 2018 to all!

The manufacturer of my class A single ended mono block power amps (Valvet) states the following: "It takes 20 to 30 minutes of warm up time for optimum sound quality. It is recommended NOT to switch off during short pauses. Leaving the E1 amps powered on all the time is o.k. from a technical standpoint but not clever with regard to heat and energy consumption." That stated, mine are turned on when I get home from work and turned off when I go to bed, every day except on week ends when they are on from morning to night. They do sound better after a couple hours "on" time.
