I am torn between getting 4 Studio 20's for the whole surround(2 sides, 2 rears). Or get the Studio 20's for the sides and the Studio ADP's for the rear surrounds. Which way should I go? I will listen to some DVD-A, how much I'm not sure. My music to HT ratio is 35/65%. BTW, When listening to DVD-A. Which speakers will be used in the the surround? The sides or the rear speakers?
