Isolate amp or stack


Hi all I have understood there is a need to try to separate/isolate audio equipment. This can be accomplished through stabilized racks and pads like from auralex. The goal theoretically is to decrease vibration and also to decrease interference between electromagnetic fields being created by the equipment. This is especially true I learned personally through record players and the sensitive needle/cartridge. Simply moving the power supply further away from the phono stage decreased the hum I was hearing through my speakers. 

The question is how important this is with separate power amps. When trying to power a multi speaker system space is a commodity and it can be difficult to place multiple amps in one space. Can you stack amps assuming they do not get too hot? I see people stacking monoblocks and seems acceptable. Is that true or if so any reason why a monoblock is more stackable than a multichannel amp? Thank you for responses.

Miller thanks for your response. I know where you're coming from with your opinions on HT. Personally I see it as a different aspect of sound reproduction. You could argue that you are not looking for the highest in highest of sound quality. You might argue that you are looking more for channel separation, speech clarity, bass response and chest slam... ie terms that you would not talk about in the 2 channel music reproduction aspect. You're also going to be able to argue that a well put together system should sound excellent and cohesive. There is overlap after all since it's just sound reproduction. In only case I don't agree that a HT enthusiast should just be written off as not caring about sound quality. Maybe they are just looking to improve their system and recreate a good theater experience for which different aspects still need to be considered. I still would not want to hear my speakers hum during a quiet passage in a movie. 

Maybe I should specify the question for both music and theater reproduction? If anything you've answered the one already. Thank you.
