@jea48 - thanks, I haven't looked at 8awg or 6awg Romex, so I didn't realize they were only available in stranded. Also, you're right on the outlets only allowing a max 10awg wire, though the Furutech outlets do have multiple inputs, so you could splay the 8awg strands into two bundles for the Furutech outlet inputs, but probably not recommended. It's best just to use a double-run of 10awg Romex if you wanted less resistance to the outlet (and keep solid-core wiring). This gives you an equivalent 7awg.
It's interesting that a single solid insulated 8awg wire is available, and individual wires could be used in this case. However, they must be run in conduit from the panel all the way to the outlet (per electrical code). Romex is the only thing that can be run bare in-walls or in attic without having to run through conduit. And your right that it's probably a freakin pain to work with (too stiff and can't bend enough at right angles). 10awg Romex is hard enough to work with.
