I have not tried that set-up, but back in the 80's I tried a pair of the Quad 63's with a British(Musical) Fidelity A1, a 20 watt Class A integrated. That system was incredible, it beat a lot of $10,000+ systems back then. The A1 then sold for $375 and back then used Quad 63's were going for about $600.
But the Sensation is much better sounding than A1 and the Quad 988 should be too, I am sure you will be wonderfully surprised on the sound quality. I see no problem that the Sensation should drive them either.
