Still evaluating the Supers and they are sounding fantastic. All of the distortion i was getting from the K55m mids is gone and can now listen on axis to my ears. I think they sound great on the floor, but haven't tried them elevated yet. Anyone with a pair of Heresy 1's should try this mod, but be sure to use a 2.0 cap on the input and #2 tap for your mid if its a K55m and klipsch autoformer. Low volume to high volume, doesn't matter, they sound so rich and clean that i can hear everything now like cymbals and breathing. With mid on tap 3 they were too distorted to hear the small things when listened to on axis to the ears and sounded much like a hollow horn if you know what i mean. Thanks for all your advice claude, you knocked it out of the park buddy.
