Brad- I know Charles was working on a ceramic tweeter, though I hadn't heard a word about it being close to finished let alone on a production model. I know the diamond tweeter is well worth it if you can at all afford it, as is the enigma crossover upgrade which I think is standard on the reference monitor. You've got to remember that focal is not going to be selling raw drivers in the not too distant future, so companies that have been using them are doing everything they can to find a new replacement. In kharma's case they decided to build there own to there specs. Your best bet would be to talk to either Jonathan or Bill and find out what's what, it surely is VERY confusing and something should be done about the vagueness of that website- in my experience it causes more questions then it answers. The other tricky thing is Bill is not importing certain configurations of kharma's for several reasons, so the only way to sort out the confusion would be to talk to a dealer who is in the know. So maybe I haven't helped you any, but its nice to see your looking down the right avenue for your next speaker :)
