10/3 or 10/2 to each outlet?

Going to have electrician install 4 dedicated lines from my main panel. If using 10/2 to the outlet, both plugs will share the same circuit. Am I better off going 10/3 wire with a hot wire to each plug and sharing the neutral and ground as in a 10/2 setup? What are the advantages or disadvantages of going 10/2 vs. 10/3 wire? Should I be looking at a subpanel with my runs going to be approx. 30-35 ft?

Outlet 1 - Dual mono amp with 2 cords
Outlet 2 - processor and Dvd player
OUtlet 3 - Cd player
Outlet 4 - Tube preamp

This is the plan, at the moment. Where would you put a 5 channel amp with the above? What would you switch around. I also will use a 1 duplex Stealth mini Digital conditioner and a Regular (3 duplex) conditioner. Would you use 10/2 to all outlets or go 10/3 with some? ANyhow, I value your insights and thank you all for the lesson in electricity. Cheers. Dave

The subpanel will be a 120/230v 60amp panel. OK? In an insulated ground scenario, do you need both an insulated ground bar in the subpanel (for red wires) and also another ground bar for the bare copper wires? Does the 6AWG from the sub to the main connect to the main grounding rod or is another rod required? By installing in the same phase or line at the subpanel, wouldn't I be overloading one side too much? In this configuration, I assume putting 5 outlet on the LT side only in the 1,3,5,7, and 9 positions. Thanks for the class Jea48, how much is the tuition? I sure have picked up alot. If you need medical advice or questions, let me know. Cheers.

If the outlets are going into plastic recept boxes, does the chassis have to be plastic too or does it have to be metal or steel? If using metal recept boxes housed in a metal chassis and bolted to the floor why do all the duplexes need to be in separate boxes? I was planning a 2 duplex chassis for the amps and a 3 duplex chassis for the components, all on separate 10/3 lines. (5 dedic. lines total). Thanks.

Jea is absolutely correct about spending the extra $ to run a ground connection feeder. If it were me, I would also size it at 6Ga. But then, I am the one who suggested being sure to check your entire grounding system to make sure it was adequate or oversized. Make sure that the ground conductors going to your ground sink are also appropriately sized.

If it were me, I would go the extra mile and use the isolated approach. Jea has very clearly shown you your options.

Question to Jea:
With putting all of the audio devices on one phase of service, do you have concerns with load balancing, or are you also using a sub-panel and balancing loads in the main panel? I am assuming from your language that you are using a sub-panel yourself. Yes? Have you wired it 120/230V or straight 120V?

The home is 10 yrs old, a 2 storey, and has an indoor grounding line. Not sure about the metallic water line but the electrician did mention he would be using some part of the water line. I'll have him clean up the whole deal. Cheers. Dave. Would you ground the subpanel at the main ground/neutral bar or would you install your own grounding bar for the sub panel? Thanks.
