Soundstage Heresy IV and Forte IV

"If you’re serious about soundstage, you can’t be serious about Klipsch."

First time hearing such a thing. The Heritage line has a huge loyal following of a lot of very experienced listeners, and a fanatical fan base, so would be interesting to hear why they would not have "soundstage" when that is nothing that we see in reviews of these speakers. I do not own Klipsch mains, but there is nothing that would keep me from adding them to my collection.

Proper listening triangle and correct toe-in Forte’s have massive soundstage in my main rig. 20 watt SET 300b driving 845 output tubes, volume pot never past 10 o’clock.  Does it sound live? Close! 

If you've never owned Klipsch....you can pick up a new pr. Heresy  IV's for $2500.....see if you like the K-sound....then , move up the line.....

None of the Klipsch Heritage line have a problem with producing soundstage. Take it from someone that owns La Scala AL5s. 

I dont mean to be unappreciative, but the question was...preface first...I have heard online that Forte Iv's have better soundstange than the H4. Is this true? If this is true, what in the Forte causes this improvement?
