I don't get Klipsch Heritage line. Some believe the stock speakers just fine, others have need to modify. As for myself, I'm in the mod camp, how anyone can put up with their timbre anomalies is beyond me (other issues I won't go into, timbre by far the worst). Klipsch should listen to the modders, institute some of those upgrades in factory versions. Most of these mods wouldn't require steep price increases, and put Klipsch in higher echelon of loudspeakers. Heritage line has some real inherent advantages, not taking advantage of them in stock form. Haven't heard the latest Heritage models, so I can't comment on whether Klipsch improving, but continuing mods lead to same conclusion.
As for the Klipsch purist. Do you believe the modders are experiencing real improvements, or is it delusion?
