Obviously I realize that no information will be revealed on the Klipsch forum here, but I am dying to know if there is to be a successor to the X line of iem's? I have been using the X5's for quite some time and really hope to be able to get my hands on a new model in the future, of a more analytical, reference, neutral armature variety, as I am not a huge fan of the huge bass of the S4's. I am wanting to get new iem's but would like to stick with Klipsch in the event there are new models coming.
