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

@roger_paul 
So what you're saying is if I go buy your amp and a pair of Bose 151's and string them together with telephone wire they'll sound better than a stack of Pass's best and a pair of Wilson Master Chronosonics? You're claiming your gear is so good that it can overcome the most beaming, broken up drivers, ill-conceived crossovers, the most reactive loads, and most resonant cabinets? I'm beyond skeptical. I'm sure you're a nice guy, but come on man! You need better answers. 

I have absolutely no doubt that you make a fine amplifier, but, unfortunately, you are starting to sound a bit like this Bo fella with his "Tru-fi" business.

Don't you think that after working on this method for 30 years that it might be something that you would at least give the benefit of the doubt to?

Its not like you went to see for yourself what this could be even if you think it is a hoax or BS. Your looking at this from the wrong end of the telescope. I'm not saying "I think" I can make a cloned copy of an event. I have the working technology already up and running.

You guys seem like a plethora of naysayers and Debbie downers.
Your wasting energy trying to tell me that I cannot do what I just did.
I'm not looking for any special praise or kudos - just to be heard and taken seriously.

The correct answer is "wow this sounds interesting but I would like to hear that for myself"
Instead "Your sounding like a crack pot or nutty professor or delusional"
"You can't do that because...bla bla bla."
"Face it we all live with some degree of distortion in the system"
And then you list 10 things that prevent me from succeeding.
All of which I have overcome.

Every attempt at "3D" without exception has involved some type of parlor trick or "enhancement" circuitry to give the listener the illusion of "surround" sound. 

Zero distortion is 3D.

I'm officially blue in the face so I think this will be my last post.
I want to thank the "other" readers of this thread that did not jump in with reasons I'm going to fail.

Seriously - good luck to those that enjoy the pleasure of listening to music without the hassle of politics or prejudices brought on by brand loyalty or designer gurus.  

Even Fox News thought this was a hoax (at first).

See you in the future.

Feel free to ship me all the gear you like! I'm more than happy to try anything that won't demolish my speakers, and even things that might. Even when I do have cash to burn, I still need to make the most cost effective purchases I can, and I know I'm not the only one here like that. In all honesty, I'm not hearing you describe a sound all that different than what I'm already hearing. Deep, wide, holographic sound is what my rig does well. A BIG part of that is the speakers. I just want realistic claims and cold hard facts I can weigh and analyze. I need to make very informed choices. 

I usually tell people that the room is 50% of the system. There's not a lot you can do with the very best system if the room sucks. Conversely a very modest system can do great things in a good room.

If you had the perfect amplifying method - a pair of Radio Shack book shelf speakers would still give you incredible imaging.

I used to work at the Allied Radio service center in Minnesota. Radio Shack speakers imaged just fine if they were set up right, even with one of their lowly receivers like the STA-76. If you put better gear on them they did even better. One of their speakers used the Lineaum tweeter; Tandy bought out Lineaum just to get the technology for a $250.00 pair of speakers. They got good reviews in TAS on that model FWIW.
