I have an idea how the Salas Simplistic RIIA with folded cacode can be transferred into a transimpedance RIAA.

I actually came up with another circuit based on the "normal" simplistic. It saves one stage and one cap. I post a conceptual schematic tomorrow.

Correction : it saves one stage but still has two caps.

Default TS

Here is the conceptual schematic of the Transimpedance Simplistic, TS in short.
The input is a high Gm transconductance stage with 160mS. This works on a low noise BJT cascode current source.
I will show you the values of the RIAA later today. With that values gain is around 66dB so there could be a volume control in the RIAA and a sensitive amp could be direct fed without a line stage.
The output buffer is from the Paradise. If we use a plus-minus supply on the buffer it could be DC coupled at the output but i think that is too much trouble for too little gain. I think a good cap at the output is just fine.
