Is Krell onto something?

Krell's latest Pre/Pro (reviewed in this month's Stereophile) features two center channel outputs, joining Magnepan in support of this, in my opinion, superior option for the most crucial (should I say 'all important') channel. An image right in the screen's center, one speaker above, one below, adds a palpable level of realism, and, after all, two (speakers and amps) don't have to work as hard as one.

Any thoughts, other than the standard 'comb filtering' argument, that does not anyway hold up to measurements, or my listening experience.
