As far as the heat is concerned, I have always seen warnings from even the most basic of receivers to at least leave a distance of 6 inches from the top, that particular amp I have no doubt is able to control much of it's heat through the heat sinks, but it's still going to produce heat moving upwards over the course of extensive listening, personally I would just rather not worry about it and keep the components away from the top of each other.
The feet I made from ceramic. Each layer is glued to the next layer so its very solid. I am thinking of putting a ceramic platform on top of the feet. I also may make more feet but only half the hight of whats under my turntable. These shorter feet would go under amp and preamp.

As far as the heat factor...there is plenty of space to the sides and the front and back for the heat to escape. After long periods of listening I touch to see if its hot and it never is. So the heat is really not a factor.

The elevation really helps improve the sound.
