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

Apart from the scientific articles that the ordinary Audiogon user does not have access to, here is the wikipedia article on auditory/echoic memory: https://en.wikipedia.org/wiki/Echoic_memory

That’s weird. I can remember what I heard for hours. Days. Even months and years. Freaky! 😳 I must have a photographic memory. 🐘

What is the distinguished scientific source used?

Oh, It’s WIKIPEDIA!!!!

Cleeds,
If you were to take some time and read some of Willemj’s prior posts/ comments you’ll recognize there are numerous unsubstantiated claims. All backed by "science " of course 😊. You are right to be wary.

Kalali I agree with your comment regarding audio components and longevity.
