The circuit in your first post looks like the JLH Moving Coil preamp, which sits in front of the RIAA equalization section.
For this purpose the input transistors are small power devices, to provide very low input impedance.

JHL also used the same circuit to drive headphones, but in this version normal small signal devices were used fro the input and the power devices located at the output.
