This may not be what the OP had in mind but I have owned many brands/models of speakers over the decades. I don't think any other brand is as dynamic as Klipsch. Transients are faster on a Klipsch. My current main speaker system is AR 3a's. They are slow and thick compared to Klipsch, but still very enjoyable. I will be in the market soon for a pair of Klipsch to partner with an 845 SET. A pair of used Forte, Chorus, or Quartet are in the running. Heresy's too, but I would prefer some more bass and a taller speaker.
