In looking at that, I am having a hard time understanding how that would work. I would think the three error amps could fight each other and not be able to do their jobs.

They are supposed to be looking on separated load nodes. Or at least that is what I thought was the idea. I would prefer to give chance to a dedicated first stage low Z active noise filter on the rail than all this complexity and dissipation non the less.

Don't know yet, I have a bunch of extremely low noise BJT types that I will have to experiment with in a future build opportunity.

Are you thinking about a cap multiplier similar to the one used in the Paerl phonostage?

Its not satisfactory for Zo. Maybe to cascade 2 Sziklai buffers.

You could use wool felt to set up the RIAA and control noise
