I'm not sure about the Elrod cords, but I've owned the Stealth and auditioned the K-S and they are very different.
The Stealth Dream is clean, fast, and tonally balanced. When used in the intended STAR grounding system it becomes "Greater than the sum of its parts" in terms of performance.
The KS Elation gives a very, very black background and remarkable midrange (but not quite the stunning, magical midrange of the Emotion). The Elation is much better in reaching the frequency extremes than the Emotion, though. I suspect that there's a scientific limitation that prevents a cable that can present the midrange the way the Emotion does from performing at the wider audible frequencies. Otherwise I think Joe Kubala and his boys would have found a way to keep that amazing midrange and reach a broader range of frequencies.
Generally speaking, I'd say the Stealth will give you more detail, while the KS will be more "musical".
