Well first of all, I don't know that buying cables to help tune in the sound of your new speakers to your existing electronics (which you are already planning to change) is a good idea. You say that you recently bought your speakers and that they don't match well with your Pass electronics. How do you know whether it is the Pass Labs electronics or the new Focal speakers that you do not like? Did you like the sound of the Pass Lab electronics with your previous speakers?
Looking to buy cables to mate with a system that you plan to change in the future is like putting the cart before the horse in my opinion. Because when you change the electronics or speakers so that they mate better, you will probably want different cables then too.
That said, I've owned both Tara Labs and Nordost cables, and while I would agree that they both offer speed and resolution, I would not say that they are also "warm" sounding. The Nordost Valhalla is the fastest sounding cable I have ever heard, but can sound a tad lean or clinical, not warm sounding at all. The Tara Labs The One that I currently have is very fast, not quite as fast as the Valhalla, but does have just a touch more musicality. I would still not call the Tara Labs cables "warm" sounding. The problem with speed and "warmth" is that they take you in separate directions. Just as one cannot go east and west at the same time, one cannot have speed and warmth at the same time. The faster the sound, the leaner the sound, while the warmer the sound, the slower the sound. I'm sure that others will disagree, as that is the nature of this hobby. However, IMHO, you should settle in on a system first before fine tuning it with cable choices.
