Component Stacking Question


Can I stack my Amp on top of my preamp ?
Will either component be negatively affected by doing this?
I have a Sherwood Amp 6040 with M0S FET push pull DC that runs warm.
My Pre Amp ...Sherwood 6020 
Components are not in a cabinet.
Thank you

Why not just get some kind of stand?

audio advisor has some stands for around $100 


Rocky, amplifiers have large power supplies which can generate noise in a low level preamp particularly if it has a phono section. It is always best to keep power amps away from low level devices. 
You might get away with it by using a platform and footers between the pre and amp with emi + rfi rejection.
