Amps on top?


I have read that an amp should not be on your top shelf, but rather on the bottom 

Is there anything to this?  Assuming a well-isolated system throughout.

@ghdprentice     I am interested in your comment on the sound improvement using ultra-short speaker cables.  I have always understood the speakers like to 'see' a bit of resistance and capacitance.   I run Krell KRS200s that stand immediately behind the speakers whose connectors are low.  So I could turn the amps around and run on less than 1 foot of cable.

Should I?

Another benefit might be that I could afford to run the most expensive speaker cable in the world.  But would it make much difference is there's only a foot of it?

Do you know the physics of all this please?

Was heard clearly .5 mi. away.

Bass?  Not likely, but was on the edge of an ordinance test range, so maybe the military filled in for the subs...

Law of science.

Heavier items at bottom, lighter ones higher up, duh. This discussion makes me feel stupid...

Roger Modjeski recommended at least two feet of air space above his Music Reference tube power amps. Lack of ventilation greatly reduces component (capacitors etc) lifespan. The companies that mount their output tubes on vertically-orientated circuit boards are apparently not concerned with that issue. I am.
