Being of the "old Klipsch fart" sect, I approve the recommendation of the Heresy II with the old HK. Better yet, if you can get away with larger speakers, the Chorus II, forte II, and Quartet were among the best monkey coffins Klipsch ever made. Saw a minty pair of Walnut forte II go for ~500 recently. Those paired with your HK would be an ultra-retro rig that would rock your face off and sound excellent while doing so.
For less sensitive, more modern speakers, I wholeheartedly recommend the Philharmonics (or Salk). They're superb.
