"Hi Josh. Visceral to who, you or Curleyques? Visceral is a very personal effect."
Hi Phaelon. That's a pretty widespread description. The dynamics in that price range typically have more bass slam. Whether this matters to someone is a matter of personal tastes. I assumed by what Curleyques said that it was one of his main priorities. But, of course, you're right -- it's subjective and it might be that he would be delighted with the bass performance with the big Maggies (the big Sound Labs are a bit out of his price range). They are no slouch in the bass, good to 25 Hz, and will beat all but very large dynamics.
My personal attitude of course is who cares, you can always add a sub, or the Maggie woofer. :-) And I much prefer the naturalism of planar bass. I haven't heard the 20.7, but the smaller 3.7 has superb bass performance.
