Love to hear te review from Josh! Heresy II are still sensational speakers in many respects. Their "bass speed" as well as their warm upper-bass and full midrange should stand as a reference for new klipsch speakers, also their tremendous dynamics. Add better resolution in the high-frequency range, maybe better imagine, and more deep-bass and you have a tremendous high-end speaker.
In my comparisons between Klf30 (20) I also liked more the H-II's midrange, its more "there", less thin and warmer. I use McIntosh gear which suits very well.
