Good afternoon Ram18,
I have not owned the 6000f’s, but, I have owned Cornwalls, 8000f’s and currently, Heresy iii’s. If you watch a LOT of movies, you MAY be happier with the 6000f’s. They dig deeper than the Heresy’s, and you may like them better for the movie effects. For 2 channel listening, at least to my ears, it is”no contest”! That’s why my Heresy iii’s are still here, and the 8000f’s are not! The 8000f’s didn’t come close to that LIVE sound in my listening room that the Heresy iii’s deliver SO much better.
