All of the posts are essentially correct except the one by Fsarc. The first Dreadnaught amp wasn't really a collaboration between myself, Jim White, and David Reich. Here's the real scoop:
I met Jim White at the Tokyo Hi-Fi show around 1998 or so. Theta wanted to get into the amplifier market. Jim White specified the feature set (up to five channels, modular design so that channels could be added, single power transformer, size, cost, power, et cetera). I designed the amp and built them a prototype. Just as I was finishing the design, Dave Reich left McCormack Audio and Theta hired him. Since they now had their own amp designer, Dave did the final production testing and made slight changes to the bias circuit and also how the input circuit switched between single-ended and balanced. That was it. The rest of the amp was my design.
