The picture is too big, so it is little fuzzy.

Here is the link to the full size :

I believe you have already built it and had the sound test.
How was it?

It looks like a Zen-Aleph. Where is the X ?

That would be the 100K in series with the 220uF cap.

I can not see any X. I see the balanced only.
The 100k and 220uF look like just a feedback.

How does this design differ from your previous Balanced PZ4 design?

It is feedback from positive output to negative input, so it must be an X.

Hi PETER!!

You might need one more cup of coffee.
I meant no "secret" communication bridge between MOSFETs of port and starboard sides.

Question To be or not to be?

All I see is two seperate amps (Zen's with Aleph current sources).
To be an X I think the sources of the IRF9610's should be attached through a divider.( Or the power gain devices of each channel attached to ground through a resistor and the junction of the resistor and gain devices of both channels attached through another resistor)
