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

@roger_paul 
Nobody.
Believes.
You.

I don't even believe you're employment claims. Even if I did I wouldn't be impressed. My best friend has a much more impressive resume. Even in you're rage-filled rant, claiming your "proof" and your "expert" status, you still have provided no actual evidence. 
"Hear is a bold statement - I am the expert in this field. Period." 
And what field is that? Amps? I don't think so. You have a confused idea that doesn't withstand any scrutiny and you're most definitely the expert in that field. Yeah, I did build an F5 clone. That hardly makes me an expert and I'm more than happy to admit that. At the same time, I know what I built and why it works the way it does and I'm doing my best to better understand the nuances of Nelson's designs because they reflect a deep understanding of the art. Nothing you've said reflects understanding. There's nothing to learn from you. You'll never be a Pass or Levinson or Colburn. You can't even prove your claims.

Why would I want to be one of those guys?
They are stuck in conventional world.
I have something far more creative.
I always think outside the box.
In a little while they are going to wish they were me.

Besides those guys and the others you did not name are running just a few years behind me right now.

I'm the happy camper.

That's because nothing I've said you understand.

The field is 3D sound reproduction.
