I've got Maggie 1.7s, they've always been good listening. And I've gone through several amps (Emotiva, Crown), and one sub (Rel). Now I have a Krell Showcase (7 channel) driving the Maggies and 4 Kinergetics subwoofers. This is it, I think! The Maggies definitely need subwoofer support, in my large room, and the acoustic suspension Kinergetics (which go low but not to high db levels) complement well. But the big deal is the Krell amp. Now the Maggies are fully alive, voices are alive, and the bass which includes the subs is to die for!
I'm surprised that I don't find more online about the Maggie/Krell combination, but maybe I just haven't enquired effectively.
PS I do have a bunch of plants in between the Maggies, diffusing the back reflected sound. Thanks to my dear wife! I think this may be important...
