I've had the set for a couple years now... (the 65, 75 fronts, and 63 rears). I agree they're quality speakers (build and sound)
It wasn't until i got my Onkyo 605 that they really shined. Apparently the Audessy 2EQ equalizer + mic is supposed to equalize to a flat response. After I did this, my horns got nice and bright/crisp. (It definately gets your attention, and I guess i was losing treble in my room without EQ)
I suggest listening to some lossless soundtracks with these guys. Two scenes in Spiderman 3 -- early scene where the hobgoblin is chasing spiderman through the city on his hoverboard, and a late scene where spiderman traps venom with metal bars and bangs them to create deafening metal clangs.
I really should find my camera and post some pics.
