That was basically my point.    I seem to recall that the 
D-104
folks were recommending a 5.1 megohm load.  That was a
very long time ago so perhaps my memory is faulty.

The discussion had seemingly gotten into a "runaway" mode
where folks were telling everyone how to make the input
impedance super duper high.  I just sat here shaking
my head and wondering why   :-)
