Separate ground for dedicated line

I would like to install a dedicated line or 2 with a separate ground. Would installing a ground rod in my crawl space and running two ground wires from the outlet (1 to the rod and the other to the main breaker box) be acceptable in terms of tying the grounds together? I am not certain where the main ground is located since the power feed to the house is buried with no exposed cables.
I need to do something as the stereo is on a noisy 14 guage lighting circuit. Thanks.

Re the shield on the belden 83800 series. If you're using the simpler 83802 12/2, then of course connect the twisted shield at both the breaker bus and your outlets' grounds.
If using 83803 12/3 then you can ignore the inner shield OR connect it at the breaker to act as a drain. RSVP for more info. Cheers.

Yes, except that you ALWAYS want to isolate the RF-noisy digital components from the low-level analogue (CDP, phono pre, tuner, etc.). So if you run only ONE dedicated line keep your CDP OFF it! Better to run two lines...one for digital and one for analog. Even better to run THREE if you have big monos, so they can have their own fatter one. RSVP for more info....Ern

Joeb, I hope Audiogon allows this response, as I resell cut lengths of Belden 8300 series cable for dedicated lines....
I would try a SHIELDED power cable for your dedicated lines, connected to better duplexes, and then use SHIELDED PCs to your components. I assemble simple power cords with inner full shield "drains" AND a SWITCHABLE outer third-wire safety ground, thus allowing you much versatility in organizing ground paths while maintaining excellent RFI protection. RSVP so I can help further. Cheers.
