If resistance per foot for this alloy is 2.94 ohms for 30 gauge, I could probably go up to 24 guage to give me some more current carrying capacity.

Yeah. Here's a chart showing the resistance per foot for a number of resistance wire alloys. The one I mentioned is the same as the MSW-294.

Major Alloy Resistance Data

Although, as you suggested, if the driver (Maggie ribbon) is dissipating 20 watts then the current is ~2.5 amps (3 ohm driver) ... so the 0.68 ohm resistor is dissipating ~4 watts.

Yeah, though I don't think you're actually going to be constantly slamming that ribbon with 20 watts. I'd guess the resistor may on average only be dissipating about a watt.

So you're positive this copper/nickel alloy resistance wire actually "sounds" good?

With the all important qualifier "to me," absolutley.

Would it sound better than just using a standard Mills ww resistor as an attenuation resistor (I've never heard any comments about the sound of Mills reses)??

I think it sounds much better than the typical nichrome that's used.
