We were kicking around the concept that the phono section should be at
the turntable instead of the preamp, indeed, if you have a stereo amp
with volume control you shouldn't need a preamp, but also because the
phono section should be close, very close, to the cartridge, as with a
tube or FET condenser mic.
What are some good solid state phono section designs? Should they
treat the cartridge as a balanced source (four wire) or not and should
plus and minus DC rails be needed or should a monopolar supply be used?
What have you readers out there built and liked?
An old idea of mine: a small SMD RIAA conversion amp built right into
the headshell or the arm.
That could be so lightweight as to almost not disturb the resonance
frequency of the arm/cart combo.
Doubtful. Regardless of how small and light the preamp is, it's
going to dramatically affect arm mass. Think SMA 3012 or
similar, not to mention ReVox arms, that are essentially just a
cartridge shell.

Differential inputs and phantom power supply.
One of these days I'm going to try that.
