I have heard the Khorus several times. A decent speaker, but to suggest it is a contender for "world's best speaker" is a joke. I own Wisdom Adrenaline 75 line source dipoles (bi-amped system with electronic crossover). These are so far superior to the Khoruses that it is ludicrous to even compare them. The Wisdoms are so resolving that they require extremely careful set-up and matching to auxiliary components to realize their capabilities. Other speakers that I have heard that are in a different league from the Talons include the top Kharma speakers (don't remember the model--they go for around $70K), and the big Pipedreams system. Probably others too, but I'll stick to what I've heard. Personally, I prefer Eggleston Andras to the Khoruses, but that might just be an *opinion*.
