Thanks for clarification Christophe!

Wow! They are not amplifiers, but a special category

Well, we are at stage 2: 'It exists, but it is not important.' '-)

"We all knew that back in 1930'Th!"

Nobody can compete against the person with this slogan John.

It better not be or you, Nelson, and Chales Hansen are in trouble! .

Please read the results, even the lowly AD712 does't register. AD797 UNDEGENERATED bi-polar, no reading, no PIM, no TIM, results even from your side. Don't get me wrong a 50 cent op-amp might be 5 orders of magnitudes DIFFERENT than a ZEN amp, I think the door is open now to find one of those euphonic colorations that causes preference. We might want add lots of PIM for the right sound after all most mechanical forms of recording are packed with it..

Scott; working on a "grand piano" effect for bass guitar I discovered that PIM is useless, it causes NASTY sound. Let's forget about "euphonic" epithets for this phenomena.

If people still prefer "you, Nelson, and Chales Hansen" let's search for the answer in the different dimensions.

Good insight. I brought this observation up to Jan at AES. All we need is a flutter generator with the right modulation spectrum to get class A sound. People seem to prefer an LP cut from a digital master to the original digital master that is not available. All you get is a collection of distortions plus noise in the lp but people love it. I have also heard that running a track through a tape recorder (in and out) to add some tape "sweetening" like flutter and noise with some saturation distortion "enhances" the sound.

We have been pursuing the wrong goal all along.

I said it last week, I don't think this will lead to many answers just having some fun. Trick or Treat!

Congratulations Demian!

Now you have a chance to start perusing an another goal. You heard already an example how Nelson speaking about added on purpose distortions even turning away from microphones sounded like Nelson speaking in the big room away from microphones, but louder. And no more distortions were needed so hear that it was Nelson Pass speaking turning away from microphones.

Let's speak of systems that work humbly, as if they don't exist at all?
