Klipsch speaker choices

Hello,
First post here but long time 2 channel guy. 

I currently have a system with Klipsch RF3 speakers and a crossover with stereo subs.  Sound is good but I think the highs and mids are still a bit edgy.  Bought a Schiit Aegir with passive preamp and see vast improvement.  All my interconnects and speaker wire have also been upgraded. I just listened to the RF7 iii but very briefly.  Initial impression is it was more laid back but I am wondering how that speaker sounds vs the Heritage box speakers.  I will probably listen to the Heresy 4 first but wondering if there is a difference in sound between the tower and the box speakers. 

I also have read about the Tekton speakers but am hesitant since I can't listen to them.  It is all over the place opinion wise about the Tektons.  The Klipsch Heresy are within driving distance for an audition.  They will have several models to listen to if I talk myself into going further up the cost ladder.  Any opinions would be greatly appreciated.
