I recently replaced a Klipsch center (THX 550), with a Revel Performa C426Be center, which closely matches my left and right front channel speakers, Revel Performa 226Be.
I had thought that Dirac, implemented on my Marantz AV10, would compensate for the differences in the Klipsch center and the Revel left and right speakers.
But, no, the front soundstage is now seamless, and I now know it was NOT before making this replacement.
Maybe it's the higher quality of the replacement speaker, partly, but I think that the near identity of the present triumvirate is the thing.
Your thoughts?
