Well first of all they sound great even with the denon.
But i have auditioned them at a dealers store with Thule power amp(not the best around,but better than denon) and everything sounded better.The soundstage,the bass control,the midrange,the high frequencies...everything.The speaker seemed to be bigger!

I was thinking a price range from 1200-1500$.

P.S.I was going to buy the Audiovector Mi3 standard,i had the money with me,but the dealer insisted that i should at least auditioned the vandys.Thank God i listened to him!
It was love at first hear,not sight! After all they are not the best looking speakers around.But their sound....OH MY GOD!!!!
I think everybody who wants to buy a speaker in this price range,should give them a look!
