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.

I ordered a set of Cornscala style "B" this week.  I am buying these without listening!!  I am not too worried about it.  This is only the 4th set of speakers I have ever owned and I think these may be the last. 
Also,  I appreciate the thoughtful and informative info I was given by all who took the time to help me.  It gave me a good first impression of the forum. 

As far as the rest of my system goes, I feel I have it really dialed in.  Even with my 20 yr old RF3 the imaging, dynamics and sound are well above average.  I can't wait to go to the next level.

Klipschorns if you have the $$ and the room.

Forte III for everyone else..........
Tubes:  I see some talk about Dared. I think that is about 1200.  Actually there are quite a few on Amazon but it's up to you if that's where you want to buy it.  I also looked at the Carver which starts at 75W and is $2750.  Carver has a 5 year warranty on the tubes.  You won't see many reviews of Carver because he made the magazines mad sometime ago.  I just upgraded from a professional amp that my friend had modded to a Schiit Aegir and I can't get over the difference.  It was $800 and is solid state Class A at 20W.  it plays plenty loud with Klipsch!!  Has great detail, mid bass and soundstaging.  I have never owned tubes.
If you have the space, forget Klipsch and try the Spatial Audio M5 Sapphire. Even their predecessors, the M4 Turbos, were far more refined than any Klipsch speaker I've heard. If you want Klipsch dynamics without sacrificing refinement, that's the route to go. This is coming from a Heresy III owner.
