That is what i mean. No doupt it is good. But i Can not stand claims of circuit designs as a selling point. Maybe it would be more in its place to describe what it sounds like and showing the beautifull designs.

I call it with humor "Double Aleph".
It is certainly an investing idea.

To make something really new that sounds better then what we have is difficult. Lets see how far we get here.

Here is the Zen 4.0
Would it be possible to run this balanced and using two positive supplies only, in the process make it DC coupled ?

A new thread for this one, but if we should be loyal to pass i would thermally couple Q1 with its mirror in a diff amp. Maybe with a resistor of 10k between Q1 and Q1a Gates...... We have a low drive impedance from the zvp3310 so this would not be a problem.

Open up a new can of worms ?
I just put this circuit online as a diversion.
What i really would like to do is making the simple symmetric as good as we can.
I have a weak spot going out of the drains. That reminds me of work i did on phono stages.
The current mode approach. It holds some promise.
My question is : what happens if we connect a real speaker and not a dummy load ?
A current output with current feedback is superbly immune to loading.

This square wave thing is nonsense though.
One of the very best and true "one-liners" ever........the pompous will murder you. Let's just hope that LC removes any OT interference from that brigade.
