To stack or not to stack - limited space for amps

I want to bi-amp with two class D SS amps. Space (shelving) is limited. I assume that it is not advisable to stack amps. However, with the amps being class D, the heat factor shouldn't be much of an issue. I was more concerned with other negative aspects?? I was considering placing one on top of the other with some form of after-market damping control (i.e.: "feet"). How bad of an idea is this? If it is doable, what type of damping product would be best utilized.

Thanks.

I think stacking Class D amps should not be a problem.

You should be able to hear a hum from the speakers if there is a problem with magnetic fields caused by the electronics. I can't stack anything without causing hum from the transformers picking up the field. Six inches away, and no hum.

The only problems this could cause would be cosmetic. Little rubber feet can leave permanent marks on the top of the lower amp.
Other potential problem lies in the fact that some speaker cables weigh more than certain Class D amps.
