SoundLab A-1 vs Martin Logan CLS IIz's

I love my tweaked Martin Logan CLS IIz's with 2 Vandersteen 2wq subs.. But I've come across a local pair of SoundLab A-1's for a decent price. Before I take the plunge, I wanted to get some feedback from people who have heard both, or have compared these speakers. What about the low end? Would I use the Vandersteens with the Sound Labs....or would they be redundant and no longer necessesary. My Logans are driven by Innersound 800W monblocks. Would these mate well with the Sound Labs. Truth be told, the WAF may impact on my final decision too...... because my rig is in our bedroom and the Sound Labs are absolute beasts.
