In my experience, Klipsch and SET sound better than anything else I've heard. However, I'm speaking primarily of the higher efficiency big horns. La Scala, Belle, Klipschorn, for example. For an analog gent such as yourself, you might consider finding a good pair of vintage La Scala's (~$1300) and a good SET amp. It will bring you into the music more than will the pentode amps, IMO. The midrange intimacy inherent to SET will not be as 'expressed' with the smaller of the Klipsch speakers.
As far as mating the Decware with the Heresy's, wait and see. You might enjoy the combo immensely.
I hope I've addressed your concerns,
