Anything better than 10 guage Romex?

What I do now is to wire directly to the panel and then terminate at the amp end with Furutech male plugs and plug into the amps.
This eleiminates several receptacles and the amp only sees one break in the line and that is at the amp.

I am wondering if anyone has used other wire besides Romex when they have run dedicated lines.

I used to use Carol stranded waterproof 10 guage wires, but I would like to try something that is shielded instead of the romex, but is also solid core.

Somewhere in a different thread someone mentioned AC wire.

I wouldn't need more than 12 feet of wire per amp,so cost per foot isn't that big an issue.

Oyaide EE/F S 2.6 seems like something I might consider, but no one up here carries it(Canada).

Just wondering what other options there are to Romex.

What I mean by better is really subjective thinking on my part.
I know that my Shunyata power cords make a difference elsewhere in my system,so I am looking for similar improvements in a cable from the panel.
Shunyata cable is not on the agenda.

My goal is to have the least connectors that I can in my system.

I see that Cardas sells a 10 guage in wall wire.

Now I have another one to decide.

The JPS is just a bit too expensive.

The wiring isn't inside the walls but is suspended off the floor and I only need two runs about 10 ft each.

One line from the 30 watt breaker at the panel,is wired to a Wattgate 20 amp receptacle and then into a Hydra 2 and that powers the amps.

The other 10 guage romex line is wired from another 30 amp breaker(on the same phase)and is wired to a potted Shunyata dual receptacle croyd receptacle and into it is a Hydra Annaconda 20 amp PC into a Hydra 8.

I am curious, after giving more information,what others feel about the best choice of wiring to be in this instance.

I wouldn't want the resolution of one brand of wire to be wiped out by the colourations of another.
Best case scenario would be wires from Shunyata I would presume.

Perhaps since they are into doing studios, they should delve into this area.
Seems like a natural to me for them.

How about some venom power cables unterminated?
