When a speaker company changes hands, particularly when it is sold by its founders, a new design team often comes on board. That can be a tricky affair. Like passing a baton in a relay race, if it's not handled smoothly, or if it's dropped, sometimes there's no catching up and the race is lost. That almost happened to giant Harman International when it bought Infinity from Arnie Nudell and Cary Christie. Both men ultimately left to pursue other ventures. It took years for Infinity to fully regain its footing, which it did with the rollout of the outstanding, high-tech Prelude system, reviewed by Joel Brinkley in the July/August 2000 issue of SGHT.
