Can I put 20 kg tube amp on top of rossini apex?

I am running rossini apex with pass xp32 and x600.8 monos.
Due to the huge heat from x600, I am planning to buy a small tube intergrated amp for a summer use.
The tube amp is 20kg and due to the space issue I want to put the tube amp on top of rossini.
I saw the picture of 17kg of rossini transport on top of rossini dac.
May I stack them with out problem?

(By the way, I do not fall for the class D amps even they are cool running and light)

I don’t think stacking should cause issues but do take care that the feet of the tube amp do not mark the Rossini is what I would make sure of.

Thanks for the info!
I will put some pad under the amp’ feet.

The weight of the amp would concern me in regard to stacking. Would I consider stacking a Rossini Transport on top of Bartok ( similar weight)? Probably not.However the main reason against stacking is electromagnetic interference. A main source of this is often transformers. Tube amplifiers have both a power transformer and output transformers.

If you are going to use a Bartok/heavy tube amp combination, my advice would be not to do this unless a solution without stacking can be found.

Transformer noise is something I did not think of. Perhaps I will give up tube amp…
