I have digital outputs from both my Sony PS3(Playstaion) and my Directv DVR. I am running 5.1 in phantom mode. I can't say that the clarity differs from one source to the other. I frequently notice that the vocals are buried in the "background" effects, but I attributed that to the mix. Also, live tv vocals (such as newscasts) are always clearer than movies.
I do not have a center channel speaker because it would be either to high or to low in front of my 72" RPTV.
