If the amp is not heavily biased toward Class A operation and doesn't idle hot it makes sense to leave it ON 24/7.
I measured the Odyssey Stratos Extreme which drew about 75-watts just sitting there idle and it wasn't very warm to the touch. I left that one ON 24/7 as it required a pretty long warmup period before sounding decent.
On the other hand, my Pass Labs X150 drew 200-watts at idle and got fairly warm. I turned that one ON in the morning and OFF at bedtime.
I have no idea how much power the A21 draws at idle but that might influence ones decision on how to manage it's ON/OFF period.
