Great!
When the first Zen amplifier was published 12 years ago, I did not particularly imagine the course the exploration would take....
......Remarkably, we seem to have made real progress. The original Zen amplifier we measured .6% harmonic distortion at 1 watt, and here we see about 1/100th of that figure. I believe that the best correlation between measured performance and subjective listening occurs with simple circuits, giving rise to the obvious question - does this sound 100 times better?
No, only about 10 times better.
What can we say more?

Wonderful job, Nelson!
I'm curious, will there be a balanced input version? I plan to run this design on my tweeter horn (500hz to 20k), but my system from the x-over forward is balanced, not single ended.
At any rate, this is sweet. I'm setting the Aleph 30 project aside for awhile.

I tried open ZV9.doc
with my WordPad program. This is what i normally use for .doc
There is an error and it wont open.
Something with the graphics.
I will have to wait for a Webpage version ( at passdiy.com ) or a PDF document
to see if there is anything new and interesting for me.
Just thought I let you know.
There can be others having same problem with actual version of ZV9.doc
/lineup - who knows how to wait, he not worry too much

I think a bridged version might suit me... However, I guess these same benifits will apply to a Pwr JFET, follower, cascoded, output arrangement??? Or does "the FET does not know what configuration it's in" not apply here???
I was working on a Circlotron circuit (follower output) lately but, it is not the output that makes the distortion in a design like that. A Zenlike voltage amp stage is the difficulty. I've been thinking the JFET might not fit into that project... Hmmm
