While work is still in progress, the amplifier was reviewed by Menno van der Veen, a well regarded tube audio designer and reviewer.
"Frank combined many techniques, resulting in a suberb sound quality. His research proved once again that the 2A3 is somewhat better than the 300B, especially when the 2A3 is driven by a low impedance cathode follower with high current capability." - Menno van der Veen
