While David's experience may hold true for the earlier NBS cables, I've found the NBS Omega to be quite neutral, getting rid of that bass thickness and the slightly rolled highs of the Monitor 0 that David notes, quite transparent and very good at conveying the soul of the music. I use it and Siltech Compass Lake in my system, and have used Valhalla as well, including all at various times between my Lamm LP2 phono stage and Jadis preamp, and can report that they're all exceptional cables, all work very well with the Lamm, just a question of overall tonal balance, system compatability and personal preference as to which sounds best to you. Haven't heard the Kharma; from what I've heard of it I'm sure it's even more expensive than the rest of these wires, though. My advice, FWIW, is to use your own ears and decide for yourself--bring the NBS in and listen to it in the Lamm system. You may or may not like them in the setup, but at least you're not letting a dealer make a very expensive (and profitable for him) choice for you. And if you like the NBS in the system, and it communicates the music best to you, then who cares if it's "colored"? Good luck!
