Default Pre-Preamp or Head Amp

Has anyone built any one of the head amps designed by Marshall Leach as found on : users.ece.gatech.edu/mleach/he... ? What do you think about the Common-Base circuit? I'd be using this to boost my Dynavector 17D2 MkII. I'm interested in your thoughts.

See the thread " Moving Coil preamp design" for discussion on the Leach preamp.
