We didn't set that as a goal, its just how it worked out. Speed is an indication of bandwidth. Wide bandwidth means correct phase relationships in the audio passband (20Hz-20KHz). We *were* interested in good phase relationships. The 600V/mS figure is a bit overboard but that is just how it panned out. A lot of people previously thought that such speeds were the preview of transistors, but with no output transformer, tubes are just as fast if not faster.
