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!

OK. So sounds like making a twisted pair of solid core still beats stranded. Good news.

Lak: the drill chuck idea is a good one. I had not thought about it. What spacing per twist should I be aiming for? 1 twist every 2 inches? Does it make a difference in sound if I use starnded cable for the ground wire only?

Thank you!

thanks Babybear.

My twisted runs will be about 25 feet long, so well under the 50 feet you recommend. Good news!
Tell me more about the flexible steel conduit: what's the purpose? Just conduit or RFI/EMI shielding as well? Do you have the counduit grounded?

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!

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