Yes, it will allow better heat exchange, i.e. allow the amp to run cooler.

If heat isn't an issue, then placing the amp under the DAC adds extra weight to the amp which is helpful when plugging in and unplugging headphones.

I would give the hottest part the most space and - if possible - the most distance to other parts.
Maybe put a metal plate between every device to further improve heat dissipation or even a silent fan behind the rack.
Most devices I know don't get hot because of load but because of the time the stay switched on, so powering everything off when not needed is probably the best you can do in any case.

It's always a good idea to check the manuals for operating temperatures as well as any recommendations for cooling (like free distances for air cooling). In a warm room you might not be able to stack at all.

Some devices have small feet that blocks airflow underneath and in those cases it can be helpful to add feet that increase the height a bit. For my MOTO M2 that I put on top of my RME ADI-2-DAC FS I bought small feet to increase airflow a little, as without I felt it was too close to the top of the ADI-2-DAC. I bought these, and I'm sure you can find similar if you want.

The correct order of stacking may be dependent on where the heatsinks are on the amplifier:

Depends on the amp. Headphone or speaker? Class A? Leaving on when not in use or switching off.

But I'd agree with others, amp on top as it will generally run hotter.

The correct order of stacking may be dependent on what you are willing to call pizza.

Seriously, just put the units with displays & controls where you can get at them. If something is too hot, space it out.

You all are perfect, thank you. It's a JDS Labs Atom stack.
