Recommendation for an audiophile speaker cord that is not "bright"?

Before trying to argue a point for which your understanding is poor, you may want some course-work in basic circuits. Let’s start with a simple exercise, an amplifier connected up to a driver with no cross-over. W.R.T. operation, it does not matter where you put the resistance in the voice-coil in that circuit, it will all behave the same .... shhh ... don’t tell anyone, but the same is true of the resistance of the output of a tube amplifier as well. The resistance in the voice-coil from a "speaker" standpoint is parasitic. It has no function in moving air, though it is critical w.r.t. proper operation of the crossover.

There is nothing "misleading" about the voice-coil resistance, though many, as you have shown, may mislead themselves into thinking it does not matter. It does. When you are completing your "education", you may want to look into "equivalent circuits" specifically one for a typical speaker driver. We use those for cross-over design. While you are there, you may want to look into how heating up the voice coil changes the parameters, especially the resistance, just as a side learning project. Somewhere along the way, hopefully, you will discover that there comes a point where reducing speaker cable resistance is pointless. I don’t put much faith in that happening, but anything is possible. Maybe you will even find out why there is a rule of thumb on dampening factor and why at some point, increasing it, has little to no benefit (but big numbers look cool on a marketing sheet).

Bus-Bars are to ensure equal loading across all capacitors, rarely for much else other than, as stated, for convenience and it looks impressive, at least where audio is concerned.

oldhvymech and others-

My friend loaned me the Nordost Valhalla 1 and 2, and Frey 2 speaker cords. Since the Nordost power cables, QSource and Qpoint had performed so well in my system, I tried these speaker cables. Apparently they were not a good fit, whether it is my ears, the acoustics of the listening room, a mismatch between the amplifier (ARC GS150) and/or Wilson Sasha DAW, or for whatever reason, although the sound was "fuller" than the lower end Transparent speaker cables I have been using, on some recordings, high frequencies were unlistenable (way too "bright").

Yes, I do work in trauma surgery, although I am doing quite a bit more research these days (getting old). The most incredible time was working at the Washington Hospital Center ER (level 1 trauma center) during the "knife and gun club" era. Although I must say that some of my friends who worked in U.S. military hospitals in Afghanistan (e.g., Helmand Province) during those days came back with shattered lives. All of us in trauma like the "rush" - many of us raced sports cars (on the track) and did other dangerous activities for thrills. Listening to music can be thrilling as well...The OP 

And there you have it.  Many people like the Nordost "detail", but many others realized along ago that they manufacture some of the brightest cables in the business.

Since cables are inherently “bright” and irritating in the wrong direction can we please write off the Nordost “brightness” as simply the 50% of those who tried them having them in the wrong direction. Is that too much to ask?
