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?

I still have to work myself trough the whole article but I find it interesting that the modulated cascode seems to have the greatest inpact on distortion factors.

Nice and elegant as always, I'd call it the Château d'Iquem of the Diyer.

Single Gain Stage with 0.003% distortion at 1W and I don't think Nelson is done with this exploration. Leaves me speachless. Also leaves me with some ideas to try.

Thanks Nelson
