I have 2 Sierra Towers *without* RAAL as my current L/R, running with a phantom center. I got a great deal on them used and love them. Also have CBM-170 as surrounds.

I'm planning on purchasing the Horizon Center and just curious if I should get it with or without the RAAL upgrade.

My gut is to just buy the better speaker, and just get it with, but wanted to make sure I'm not making an obvious mistake.
