I don't have any good corners for the Khorns, but that really isn't a problem because more than likely I am going to be sealing them off. I will be going to a local Klipsch dealer that has both the Reference line and the Heritage line and I will make a comparison between them. I listen to mostly Trance, so that should be a test of how good the RF-7II or the Khorns can keep up with electronica. I currently have a set of the Klipsch RF-52, but I am either moving it into the bedroom or maybe selling them off and replacing them with a pair of Heresy's. Much of it will depend if I like the Heritage line or not. When I was at Best Buy, I had a chance to audition some other's; Martin Logans, Def Techs, Energys, and Bowers & Wilkens. All of them were auditioned through a Pioneer Elite SC-37, with my USB stick. All .mp3's were 320kbps. Song's listened to were Hed Kandi - Seemingly Sleeping, Hed Kandi - Beautiful, DJ Tiesto - Forever Today, DJ Tiesto - Sweet Misery, and Armin Van Buuren - Burned With Desire.
Here is what I thought of them....
Martin Logan Motion 12 - Sounded like crap! They sounded muffled and not clean at all. I believe my Klipsch 5.1 Promedia speakers did a better job!
Def Tech ( I forget which model, but it was one of the floor standing models) - It sounded a little thin, but cleaner. Better than the ML.
Energy's ( again I forget which model, but it was a floor standing model) - Again, it sounded thin, but bright and clean. On par or a little better than the Def Techs.
B&W 684B - These took it! They played cleanly, even at reference volume. Their imaging was excellent my brother and I had to double check to see if the center channel was on! The bass was lacking but the midrange and highs all but made up for it. It reproduced all the vocals nice and clean. Highs and mids have a very good balance between them. None of which was overpowering the other. They sounded airy, like if you were in the middle of a concert.
When I got home, since the B&W's were fresh, I immediately powered up my RF-52's and made the comparison. My RF's played everything a little cleaner. All the details were more alive and detailed, the bass had more authority than the B&W's. The only drawback was that my RF's didn't sound as full as the B&W, and because of the horns, they were brighter more in your face like if you were in the front of a concert, and not airy like the B&W's.
I've been having the upgrade itch for a long time so hopefully after this I will not have to upgrade my speakers ever again, thus that is the reason why I am considering the Heritage line.
