You are asking two different questions:
1) Will the amp drive the speakers properly. That is the same as asking can the amp drive a load that varies from 3 ohms to 30 ohms properly, because that is what happens with the Soundlabs as they are currently configured -- the 3 ohms is up high and the 30 ohms is down low. That is why transistor amps do such a lousy job with the Soundlabs of reproducing bass properly and why the Atma-Sphere MA2 that delivers constant power at different impedance levels does so well (it also prefers a high impedance load).
2) Can the Soundlabs play dynamically? The Soundlabs do many things well -- as well or better than anything out there. Handling very dynamic music and reproducing concert level bass are certainly not two of those. 105 dB is the the theoretical compression point of Soundlabs. I have never been able to achieve that level of sound pressure even with 440 watts of Atma-sphere power. But for Pink Floyd to be listened to properly, you need a system that can reproduce transients way above that level. Furthermore, the Soundlabs cannot handle bass reproduction even near that level without setting the membrane a flapping.
