In our listening tests, both of the new cables had somewhat better low end articulation, and more air. The GC-2 has a noticeably lower floor which allows a cleaner view of the soundstage and sounds, uhhh, quicker. All three cables have a very similar musical midrange and a strong family resemblance.
Please note the differences mentioned above are gleaned from a direct comparison. And though there are differences I would be very happy to live with any of those three cables. They all are very musical cables that within a short time immerse you in the music and far away from furrowed brow analysis.
Or put another way, would I flip one cable for another. The short answer is no. But if I were starting from scratch you now have options. If that makes any sense.
