Physically Separate Amp from Other Equipment????

Is there any value in separating my amp from my other pieces of equipment (Spectron Musician II)? By this, I mean that I am considering moving my amp to the bottom shelf of my rack while keeping my Dac and Preamp/Transport combo on the top two shelves. That would mean that instead of having only 5 inches or so between my amp and the rest of my equipment, I might have almost two feet between the amp and the rest of my equipment. Will it make any difference????
