DIY Speaker wire


I have read multiple posts about using 10 awg solid core copper wire for speaker wire. Anybody use 10-3 romex? It has 3 shielded wires and one bare inside a plastic sheath. I am bi- ampping and am considering using this for each side instead of (4) single wires.

since I have to run 25 feet, might I braid a larger wire, say 12 awg? Also Since they are over a stone floor I thought I would put them into a "wiremold" floor raceway that has 5 tracks made of aluminum. What about polyester expandable sleeving? I've also seen posts where rather than binding posts , solid copper is hammered into a loop.
Check this out.

Just bought a 200 feet roll of Techflex 3/8" fiberglass braided sheathing for $40 on clearance.
OMG, you mean you guys are actually using impure cables! OMG, OMG, what's next!

So nice of you guys to bring some sanity from (some) of those that have drunken of the Kool-aid.

Go forth with your impurities and fight the good fight!
What about using solid core thermostat wire as speaker cable?

I saw this mentioned on the net before and seemed like something fun and inexpensive to try out.
Ngjockey,
I just ordered 4 sets of your silver plated copper wire to run in while I braid 750 feet of solid core (THHN thanks Grannying and Mechens!) I'm thinking this project might just bE DIWF (do it with friends) instead of DIY....
