I don't wish to sound like a heretic ....but I having recently spent time with a friends Heresey set up, I was underwhelmed. Always liked the look, concept, size and history of the model but...
They just seem lacking. In a perfect world (any Klipsch wigs reading?), I'd love to see a 21rst century reimagining of the model. A three way design has in my opinion always produced the smoothest sound. A rethought Heresey of roughly the same height and width but perhaps twice as deep (or more to fill in the missing bass), with a modern cermatillic woofer and a Reference tweeter would be just the ticket. Something to bridge the gap between bookshelf and floorstander.
Sort of a Heresy Millenium/palladium.
Just sayin'
