I listen to primarily classic rock and 80's/90's college alternative. I've been running Klipsch Fortes for the past 18 months, but have always been curious about Zu's and Tekton's. I was able to pick up some used Omen's 3 weeks ago.
As much as I want to love the Omens - they look better, they take up less space, I've read so many great things, etc. - I believe I have concluded that with my room and my gear, the Fortes are a better, more live-sounding, more impactful speaker. They just give me more "rock." Now, I have an Outlaw sub (perhaps not a great sub) that I'm using with the Zu's, but I wouldn't say I've done a perfect job of blending the sub with the Zu's, either placement or levels. It is definitely true that the Forte's go much lower with more authority. Maybe if I got the sub set up properly, the Zu's would shine.
I have never heard Magnepans, so I can't opine on them.
