Are future improvements in Amp/PreAmps slowing to a crawl?

kosst,
I told you that this would be good news for some and bad news for others. You are making my point.

Roger. You're a liar. You make technical claims that simple don't exist. It's not news to anybody. 

kosst,
Don't you think it would have been wise to wait until the gentlemen from PA was here to verify if this is in fact for real or a hoax?

Practically everybody who builds one applies some positive phase second order distortion through the NFB loop balance to warm the sound up and open up the stage.

There is your red flag.

No, I don't see how his observations are relevant at all. Unless he has calibrated microphones for ears, oscilloscopes for eyes, and a distortion analyzer for a brain, he cannot substantiate your claims. He doesn't know what a 100% distortion-free amp sounds like. He's never heard one. And you have never built or measured one.
