DIY head amp


Has anyone built any one of the head amps designed by Marshall Leach as found on : http://users.ece.gatech.edu/mleach/headamp/ ? 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.

Anyone know if you can buy one of these things if you are not a diy kinda guy? Nothing on ebay.
