Center & Rears To Match Avalon Indra?

After a long, exhausting speaker search, I have decided on the Avalon Indras. These speakers are really magical... The problem is, the only center channel in the Avalon line is the Symbol, which sounds harsh and unappealing to me. I have always been told that it is best to match the fronts, rears, and centers with the same brand, but in this case, it may not be possible. Does anyone have any suggestions for a center and rears that will timbre match the Indras?
Indras would match and just use phantom for center if the speaker gets in the way of the screen
Check out Isophon FRC, I heard the Arabbas at the CES along with the Indras and in my opinion both the Indras and Arabbas were my favorites.
