dedicated electrical line

You should look into installing a dedicated ground as well.

Get r' done!

"You should look into installing a dedicated ground as well."

When you say "dedicated ground" do you mean a separate line back to ground (which most dedicated circuits would have anyway) or a separate ground rod?

Both . It is called an 'isolated ground'.
Quite often found on sensitive equipment in hospitals and computer rooms .
WARNING , not every electrician knows how to install an isolated ground correctly !
While dedicated lines and isolated grounds will give you maximum performance , they are only needed if you are having problems that will be alleviated by their use . Can you hear noise on your system when appliances cycle on and off such as your HVAC , refridgerator , microwave , small kitchen appliances or flourecent lights ?
Can you unplug items that are on the same circuit as your audio equipment during listening sessions ?

If you do need to run dedicated lines , do at least two 20 amp circuits , one for your analog equipment and one for digital .

Good luck .

Hi, An isolated ground would require a separate grounding rod(s). What you need to do is disconnect the ground currently going to your receptacle, and simply run a 8 GA or 6 GA from your newly installed grounding rod(s) to the ground on the receptacle.
