In time all things change, some for the better, some for the worse. All sorts of comparisons between the old and new will persist with proponents on both sides.

My impression of the current Kappa's is positive. Some may persist with comparisons to earlier models, and in truth, there are merits to some arguments on both sides. With excellent resolution and openness, wide sound staging, controlled dynamic response, and the ability to transport one from their listening room to a performance, I believe the current Kappa's show all the markings of a good quality loudspeaker. If simpler, more cost effective designs can serve musical fidelity without significant diminishing returns, then that is good engineering.

Infinity has changed, true, but if the goal is still fidelity, has it really changed?
