Main vs. sub panel for dedicated lines

@jea48  @lowrider57  I will consult with my electrician on the amperage supply to the sub panel and the need for sub panel ground rod.

Regarding audio quality would I benefit from running my system through a sub panel that only serves low amperage devices, my amplifier likely the highest one, over running it off the main panel to which the sub panel is attached?   

SQ has been debated, but keep the audio system together on the same leg (phase).

Yes, I intend to do so.

It is cheaper by far for the electrician to just drive two ground rods and be done with it.

Exactly what my electrician said when we replaced the water main copper with plastic.

I have a new service panel and a subpanel. When the sub was installed, a second ground rod was added. Two different electricians installed the panels, both said two ground rods were required to meet PA code.

@lowrider57

Two rods yes. Both should be for the main electrical service panel.
(Reason for two as I described in my post above.)

If you would, go out side where the two ground rods are located and look if you see only one bare ground wire going into the house and not two ground wires.

The correct installation, the two rods shall be a minimum of 6ft apart from one another. The two rods are connected together with a ground wire that is then extended into the house and connects to the service entrance neutral conductor buss bar. The neutral bus bar is bonded/connected to the panel metal enclosure.
The two rods are counted as one Grounding Electrode, (NEC).
