Most of my friends that are klipsch lovers seem to like their classic lines better than their slimmer tower reference series that they have now and I am pretty sure that is why they still make some of the classic series even today. I do have one friend who likes the new series better but his musical tastes are very set on one type of music and it seems the reference series sounds better to him but it seems like the newer reference series seems to lean toward the theater end of things more than the music and the classic obviously is more towards 2 channel which might be part of what you are hearing. I have heard several models in the Klipsch lineup and with what I have heard you would have to step up in the Klipsch series to get an all musical based speaker like you are used to. Plus the horns on the classic lines are much bigger and seem to give a more pronounced high end which it sounds like you are a fan of. Burn in can be a factor when getting new speakers but after hours of listening if you are not hearing what you like then it is either the speakers just aren't for you, the receiver is not mating well with the speakers or in your listening room the acoustics just plain sound better with your classic Klipsch speakers. I would just listen close and go with what your ears tell you and if they tell you that your present speakers sound better than your new ones then that is that and the only place to go there is to move up the Klipsch line until you find something that rivals what you have but also keeps what you liked with you current speakers.
