We've never discussed Klipsch to my knowledge...
That was the only review I could find with a quick look and as AOS has numerous posts regarding the Heresy, so I thought I'd link to it for a giggle as it was a more recent pair. I heard the earlier 'II' ones extensively too back in the day and disliked the shouty screechy sound they can give unless carefully used.
Oh, a pair of Klipschorns I heard in Northampton in the mid noughties sounded absolutely amazing with not advanced amps driving them, but they're huge for most UK domestic rooms...
I have heard the cheaper models too in fairly recent times by the way, but they're still a bit too 'shouty' up top for typical UK domestic consumption we thought at the time. Admittedly not tried with NVA amps though.
Hanging on in quiet desperation is the English way...The time has gone, The song is over, Thought I'd something more to say...
