The original ZEN Amplifier is simple but great.
But can need a preamp.
Here is where Bride Of ZEN comes in.
I have simulated a circuit which joins Bride with ZEN.
I have reduced gain of the ZEN to x2 and let the voltage gain be done by the Bride.
I reduced the supply of Bride to 40V, so the combo needs only one supply.
THD shows a pretty good figure.
