I've never found Klipsch speakers, whether from the Heritage Series or Reference Series, to be overly sensitive to amplifier output impedance. In fact, in the horn-loaded units such as the LaScalas, Khorns, etc., it seems to make no audible difference at all. An interesting take on df was given by George Augspurger of JBL fame back in '67. It's a worthwhile read as is a follow-up to his paper by John Murphy in part 2. As to speaker impedance variations over the audio spectrum affecting amps, triodes with a very low plate resistance are really quite immune.
