Klipsch Heritage Range

Oddiofyl,

Can you give some details between the sound differences on the III and IV?

I did a quick demo with the III with my own music but on a receiver and I was not very impressed but I blame the electronics. 

Bill - thanks for the heads-up!

I had the heresy iv for a few weeks to audition and unfortunately was not happy with them. They are highly rated by the likes of Steve Guttenberg and Andrew Robinson on yt. I'm not saying those guys know what's the "best" but they have raving reviews if you have to time to watch. Personally I found the sound too forward and in your face. They are not a neutral pair. I actually found them very fatiguing which those two reviewers above both said the exact opposite. I found the midrange to be most lacking. I was also very distracted by them being placed floor level so I could not stop feeling like the noise was coming up from the ground rather than straight into my ears. The one big plus is their sensitivity which is just unmatched in the industry. 

JWL - when you had the IVs, what amp were you using, and did they have much time on them prior to your two weeks?

The IV sound more open.  A little less forward.  I think the new mid driver is much better than the III driver , very detailed.   Vocals are much more intelligible.   Tweeter / Mid coherence is improved

I did not spend much time with the III.   They were unavailable so I just left a deposit to secure my trade on the IVs and they called me when they arrived ..... I bought the IV sight unseen.
