Sound-Lab M1 and A1 will work with that amp in a reasonably sized room (not gigantic), provided 80 to 90 DB is sufficient max SPL. The need for power goes up on Sound-Lab as you increase volume and suffer insertion and compression losses.
Max volume with Sound-Lab is about 105 DB but requires 750 to 1200 watts per channel to maintain dynamics available at lower levels. Great sound at moderate levels were obtained in my room with Sound-Lab Ultimate 1's driven with a pair of Viva Aurora SET's that only produced 21 watts per channel.
Might be possible to squeeze more SPL with low power if the Sound-Lab is not required to do deep bass. It's certainly true bass requires more energy and Sound-Lab has rising impedance in the bass (about 30 ohms down deep). Making it difficult for transistor amps (and many tube amps) to produce enough juice.
Also, if the Entec subs crossover restricts low frequency in favor of the sub, the amps will have an easier time, although coherency will be damaged as the Sound-Lab is pretty much prefect in that area.
