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

Anyone on this thread own one?
I noticed they are not cheap.

kosst,

You see - all forms of distortion start off as phase shift or timing issues."
WRONG. Just because a distortion wave form appears slightly phase shifted from the fundamental does not mean that the phase shift causes it.

I'm amazed every time I mention something you seem to see it from the wrong angle or something. I'm not trying to be difficult but let me clarify what I mean.
in particular..

...does not mean that the phase shift causes it.

Just the opposite - the distortion caused the phase shift - not the other way around.

When I say I'm tightly monitoring the phase of the fundamental - I am watching for the first sign that something has gone wrong.
That is the canary in the coal mine. By stopping the phase shift - you have cut off any means of generating harmonics.

@roger_paul 
Oh really??? So what do you do if the distortion has no phase shift? And explain to me exactly how a low order distortion mode changes frequency as you claim. 

@roger_paul 
Look. I know you're going to say something dumb or just make up some crap that makes zero sense. You are very confused about several things and you lack a grasp on some very basic tenants of electronics. You refuse to acknowledge the well proven mechanisms of nonlinear gain and substitute your unproven theories. Without measurements, a viable theory, or a schematic you're claims should be strongly doubted. I honestly wonder if you're not ripping off somebody else's work and hocking it as your own. There's no way you're designing amps really worth $10,000 with the understanding you exhibit. You can't even identity propagation delay. 

kosst,

 Sorry kosst - you will just have to find out on your own what I have accomplish when you read the reviews or see it at a show. Good luck with your personal issues. I hope things work out ok for you.
