To tell you the truth I love them both dearly for different things.
I use my Superluxes in small clubs mainly although I did tape a festival with them and think they sound great out doors. I have run the 483's in pretty much every environment and like their results, yet prefer the cards in the smaller rooms (Funk Box baltimore)
I am a fan of both and don't think I'll ever get rid of the Superluxes unless I find a set of CK61's for dirt cheap. But the Stingray is taking all my gear money and will be for quite some time.
I'll repeat what I said earlier. Go with your gut instinct. Listen tou your ears cause they are the only thing that matters we all hear differently. If you like what you got then your one up on all the gear sluts who don't know whether to shit, piss, or jerk off.
