Single plug dedicated circuit?

By the same logic all devices "contaminate" each other in the service box and then the grid. Best have each source in different states than the amp.

Well… maybe I am missing something. But a dedicated circuit is just that… no additional outlets… that is the point. Now, it is terminated in a duplex receptacle… and you can choose to only use one of the outlets.

I have two dedicated lines… one which has my power conditioner plugged in (with all my non-amp audio equipment), and one for my amp. In the first case I use my mono blocks sometime and use both outlets and sometimes I use my stereo amp and only use one outlet.

But the point of a dedicated line is that, first, there are no other outlets connected to it that might add noise (think about a hair drier), and second the circuit does not wander all over the house acting like an antenna picking up noise.

So the only thing of real value here is a 10 gauge wire to ensure there's plenty of unimpeded impulse power for all the frequency demands. Even if you run a hair dryer it's still gonna spread throughout the panel and contaminate component. Maybe a sub panel would be a lot better. Or maybe buying a new dog as long as he doesn't bark all the time.

As you stated, a dedicated line can be contaminated at the service panel even if it’s on a different leg than other AC devices. The problem with a subpanel is that it’s tapped off the main panel. The ultimate subpanel would have it’s own line run from outside and its own ground. But that wouldn't be Kosher.
