stacking dac+transport inbetween shelves

Due to limited space in my audio rack I like to re-locate my PWT and place it ón the DSD.

This combo will fit on one shelve and will leave about 10mm space inbetween the top of the PWT and bottom of the top shelve carrying my record player.

Is this OK - or should I need more ventilation?

I expect they would be fine. These two pieces generate very little heat.

I am doing just that without any consequence. I have the DS on top of the PWT though... I feel like it gives the PWT a little more barrier[the weight of it] from any unwanted resonances thereby cutting down on vibrations from the rack itself or any air*borne influences...

Thank you - OK!, I’ll try placing DS on PWT.
