I just heard more from Wendell. He writes,
"BTW -- I would not call the first speakers 'prototypes' since it implies changes might be coming (which is not true).
"Since the 30.7 is so big and complicated, the safe process is to take one speaker through from start to finish. If there is a hitch (which there always is), there is little wasted effort. Large quantities begin after all the bugs are worked out. A flagship model has to be perfect from the start. It is better to have the criticism for it taking so long than to hurry."
