Currently my front soundstage has my center channel sitting on top of my RPTV (this is the only place it can fit) and my main channel speakers, which are towers, sitting off to the sides, about 4' away from the TV. Looking at Dolby Lab's web site they suggest that all front sound stage speakers sit at the same height. My RPTV has two book shelves bookending it. These are substantial shelves and are the exact same height as my TV. Question, for HT only, would I get a better front sound stage by moving to quality bookshelf speakers and placing them the same height as my center?
