I would also like to add how much I appreciated Andrew Jones' representation of the Mo-Fi speaker at Capital Audiofest. He does a terrific job of explaining the design, including engineering challenges and the compromises that are made in implementing the particular design. He has been my favorite representative from when I first heard him at CES talking about TAD speakers about 20 years ago.
It is a small wonder how he manages to keep his very friendly and engaging demeanor over the entirety of a long show. He is an extraordinary trooper.
