gotcha!Let me try to see how it simulates and I will get back to you.
Hey... do you doubt my simulator?

just a question:
on the servo that feeds the input, isn't this going to affect loading on the cartridge?
Let's say, ideal loading on the cartridge is 100ohm, then each side should have 200ohm.
Now with the resistor in series aren't we creating asymmetric condition for the cartridge to work off from?

I actually do really like this I am just wondering if we would like to work on the current mirrors and output buffer eventually.
I feel like ouput stage could be selected better.
I will do some listening tests with the Kelvin's buffer and see if it sounds any better than the simple one and eventually include it on the common schematic.
There is 100 Ohm both sides, as that was in your original drawing, there is no problem if you halve the resistor values (3 x 50 and 2 x 100 Ohm) the servo will still work, and the servo output filter will go from 1.5 to 3 Hz (and that is fine too).
But why not leave the 200 Ohm 'standard' loading, and add a resistor of 200 Ohm in parallel to the cartridge to get 100 Ohm loading, by providing a place to add this loading resistor it is easy to change to loading by changing just one resistor, and you can go from 200 Ohm to (almost) zero (we must allow for trace and wiring resistance).
Think I need pants with flared legs for that one, polyester and in ugly brown with thin white stripes.
Ooh, and lacquered ankle boots with a zipper.
