Lets talk dedicated lines


About a year ago I installed a dedicated 20 amp line for my system...and went as far as modding the whole power structure from the street transformer to my panel to my house...at some fairly major expense. The result was certainly an improvement for my system.
Recently i got to thinking that a lot of us have a system that utilizes the standard 15amp line that more than likely only supplies one other component in our rooms...and that is the lights. While lights can be noisy on the system, particularly if they are halogens, then this is a source of considerable hash and noise. However, since the only other thing shared by this line are the lights...and not the more power hungry grabbing stuff..like the refrigerator, or the Ac etc, then simply playing the system in the dark should essentially allow for a dedicated line effect to materialize on the gear that is attached to this line as well. The standard room convenience outlet( which is what we are talking about here) is 15 amp breaker protected and is only supplying the lights and the convenience outlet in a room....so ( assuming that this is the case--and the lights are the only thing supplied besides the outlet) what is the real advantage to the 'true' dedicated line ? Twenty amps is more than a lot of auto gear needs, so I doubt that is the issue...thoughts?

Good observations Daveyf. I have lived in houses where I had dedicated lines and without, always used the same panamax conditioner surge protector and I have never noticed a difference. As long as you don’t have a lot of other things plugged into those outlets most systems will work fine. If you run mono 1.25 kw McIntosh amps or something you might need a dedicated line. Never had ground loops or noise problems. Unless you have a noise problem it’s not worth the expense as background noise is usually around 30db flipping breakers and other nonsense isn’t going to do anything you could hear except in your imagination.
Meet Mr Irony. Irony is the expression of language that means the opposite. So for example one guy actually does something and actually hears and relates this actual experience. Another guy then imagines something different and shares his imaginary experience about something he knows absolutely nothing about, seeing as he never experienced it himself. Yet proceeds to act as if his imagination is reality. Which is ironic. 

Mr Irony. I like it. Just might stick.

Okay so here is my rig before my rig.
I am fortunate that my breaker.panel is 25' away from my system.
10 guage marine grade 1000 volt insulation wire to the monoblock amps outlet (Hubble hospital grade I may add).
Then I distribute the subs and source after amps.No noise no hum no ground loop none of that exists.
We don't need nuclear power plants for our HiFi systems, just common sense practices.
Happy Listening
