Can Power mono amps be too close to the speaker

I have the possibilty to place my amps outside/inside/behinde the speakers, but what is the best place(as I have tubes) and do I need a stands to get the amps up in the speaker connection level (0,7m) to get them as short as possible?
Marakanetz, how do you do? Is there any photos you know about here on the internet that shows so close connections?
So close connections give you the possibility to by the absolut best speakerwires who exist, WOW WOW!!!!!!!!(offcause I know that I have to spend more money on long interconect cables)

how can you get them so close too the speakers? Do you have any special stands for the amps? I would realy like to see, how you conect them. I have Cary Audio with very big trafo's and I put them about 0.75m away, one friend of mine told me he could hear some noise from the trafo´s in the speakers, maybe he isn't right!!!!!! I have ProAc studio 250 speakers and the conectors behind is in a hight of 0,7m.

Marakanetz, now I have spend 1 hour on the web site you recommend. It is an interesting website but "I havn't found what I am looking for" citat U2. I think the solusion is to buy a very solid pair of stands for speakers, fill them with sand and change the top plate. So I have two stands for my MONO amps.
