Just upgraded my system from def tech to Monitor Audio Gold 20's, 10's and center. I can get the 60's for about another $700 for the pair. Is there a big improvement from the 20's to the 60's? I cant imagine them being any better as the 20's are incredible. They are not even burned in yet and they sound unreal with music and movies. The 10's in the rear are also incredible. Just watched Moulin Rouge and it was phenominal! Just dont know if I should return the 20's and get the 60s..not sure if there would be a $700 difference. ANyone try both or have the 60's?
