dedicated line: 10AWG stranded or 2 solid cores?

I'm in the process of installing 2 dedicated power lines. From what I've been reading 10 AWG solid core, like VH Audio's cryoed Romex, would be optimal. However, in this part of the World we don't manufacture that kind of wire and I only found 10 AWG copper solid core monoconductor insulated in PVC, unshielded.

Hence my question: would I be better off by installing 10 AWG stranded cable, or taking 2 10 AWG solid core monoconductors putting them side by side + a stranded cable for ground and use them as if they were one line?

Thank you!

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.

Stenersr,
So you liked Analysis Plus better than Romex? Is the former stranded?

In some respects yes...it is a little bit more difuse or less edgy than Romex. That is the impression before either of them are broken in.

But then again, some equipment benefits from that characteristic and others do not need it. This required a little more thought into where I wanted AP capble vs Romex pulled. To have some flexibility, there was an AP cable run to one of the dual gang box and Romex run to the other.
