From my own personal experience and Alan mentioned about being able to boost the centre channel in the receiver is a big deal. I find source material to be very inconsistent with how the centre is mixed more than any other aspect in the soundtracks. Sometimes it is mixed much to low or to high where it blows you away. Having that type of flexibility to adjust the centre channel volume is great with a dedicated center especialyy if you watch a lot of tv where the sound program material varies dramatically from channel to channel and even from program to program on the exact same station.
