I suspect that the Absolare push pull amplifiers is better suited for your speakers than their SET amplifier, particularly given the traits you desire.
I don't know how different these 2 amplifiers compare sonically, same brand but different topologies. Your speakers dip to 2 ohms in the bass region, you may be better off with a high current transistor amplifiers for your needs. My friend made the switch to SS amplifiers for this very reason. In theory it makes perfect sense but the beautiful musically and emotional involvement just is not the same. It becomes a question of what qualities are most important to you. Based on your stated desire for slam and speed with your Wilsons, SS may be the direction to follow.
