I have owned all of the Klipsch models mentioned. I just recently sold, locally, a pair of self modified ( I modify everything ) Epic CF2s ( the best out of the 4 Epic models, imo ), but, just like the 2 pair of Heresys I still own, I was not listening to them, as I have multiple systems set up. The Epic series was a different animal for Klipsch, and were a good design. Roy Delgado ( Epic designer ) is still with Klipsch, as far as I know ). Parts for them are hard to come by if needed. My Lascala system is the one that brings me my " joy of listening ". The biggest upgrade you can make to a Klipsch speaker ( any model ), is to heavily dampen the horn, using a material such dynamat. However, any upgrade takes them further. And yes, I am saying it ( as I have said elsewhere ) that all Klipsch were manufactured with a specified price point, and that all can be taken to a much higher level with upgrades and mods. My favorite Klipsch models have always been the Khorn, Belle, and Lascala. As a semi retired, single ( divorced ) man, I have free reign of any room. Any Klipsch lover should go to the Klipsch forums. Enough of my gab. Enjoy all. MrD.
