At the risk of being totally predictable, I think you'd find a pair of full-sized Sound Labs to be a worthwhile upgrade over the Quads. And as a former Thor dealer, I'm quite confident your big Thor amps could drive 'em. Several of my customers are former Quad 988 or 989 owners, and I'm a former 63 and 57 owner.
Best of luck in your quest!
