i use the sa.
took a while to get it dialed in, but the bass has better attack and more body (but I have some of the big room problems already addressed). I also took some time & effort to get a speaker cable that was better for the low end than the one I was using for my mains--Nordost SPM that was a biwire set... at first, I used one side of the bi-wire for the mains & one side for the second voice coil, but whil eI love the spms for mids & highs, they didn't do the low end justice.
