dedicated line: 10AWG stranded or 2 solid cores?

Isn't "Greenfield Conduit" solid core wire already twisted in the metal jacket? Black-White-Green all insulated.

The conduit is again useful for helping to reduce the effects of RFI/EMF. Check my system page for a little more info on what I did.

The flexible metal conduit is also called "Greenfield". Its purpose is to protect the wires inside. It also provides shielding from RFI. Greenfield needs to be deburred after cutting to length, in order to remove sharp burrs that could nick the wires. You also need to use the proper connectors. You could use type MC cable (metal clad cable) that comes with the twisted wires already installed. Even that needs to be cut carefully so as not to damage the wires inside, and you need to install insulating bushings on the ends to protect the wires from the sharp edges of the metal jacket. My advice is to hire an electrician to get it done right.

Babybear,

That is a GREAT system! Very nice job on the room and power supply.
I can get something similar to the Greenfield flexible conduit around here. I guess I want to run 2 parallel conduits, one for each dedicated line. Does the conduit need to be connected to ground to maximize the RFI/EMI shielding effect?

Gbart: I've taken note of deburring. Thanks for the tip! Is the purpose of the insulating bushings to electrically insulate the conduit from the box, or to protect the cable from getting nipped by burrs?

Keep it coming!

I have tried both Romex and Analysis Plus running from an Isoclean dedicated panel to the outlets. There is definitely a difference in sound. My belief is that the amount of difference is based on the overall combination of system components. That may also mean that there are multiple ways to achieve the same result.
