Dedicated line question


If a piece of equipment requires a dedicated line/ outlet, is it imperative that that outlet be directly connected to its own breaker, or is it no different than if say one breaker/ fuse impacted 6 outlets but the other 5 outlets had and would never have anything plugged into them?

At the very least a unique breaker & wire.
On the phase with fewest or no motors.
Required or recommended? What is it? 

The primary intent of a dedicated line in audio is to allow nothing else on the line to add noise on the line. Having a separate breaker helps the separation. Also, not having all that extra wire strung all over the place allows less picking up of stray emf. 
Is this a audio noise concern or capacity issue?





Sorry the question I
is focused purely on electrical draw. I’m aware of all the preferences around noise etc. this is just my lack of knowledge of electrical. I’m guessing if nothing else is ever drawing current on the other outlets and I’m supposed to have a dedicated line that from a pure power pull perspective it’s no different ?
