When it comes to amplifying small signals one does not need power or necessarily gain.
One needs low noise figure.
The first stage will dictate the noise performance of the whole system. Any noise generated there will be subsequently magnified by all further stages. More on the Pleiades low noise battery electron tube amplifiers on other euroelectron posts.
