I run a Son of Ampzilla 2000 with my Modwright 9.0SE (Signature Truth). IMO, it's a superb amp. You might be able to find a used one for $1500, or so.
Of the three you've listed I'd probably lean toward the DNA, as I prefer the sonics of conventional amps. I'd highly recommend looking at the Modwright Signature Truth mods. They are a significant improvement over the base SE.
