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

Sure, you need to have enough power (and for top level speakers lots of power), and the frequency response has to load independent (within 0.2 dB for your speakers). Both require a beefy (and hence more expensive) power supply. Even so, this can be achieved at relatively modest cost if you avoid boutique brands. Look here for an example: http://www.homecinema-fr.com/forum/amplificateurs-de-puissance-haute-fidelite/mesures-ampli-yamaha-p3500s-mise-a-jour-t30056383.html

Sorry boys your wrong. This is what you believe because you have no reference when it comes to hearing what a distortion free amplifier can do.

I have the evidence of what I speak. I realize it might be hard to imagine that such a breakthrough in sound reproduction can come along but its here.

I have actually cloned the original sound event (concert hall) and I can drop that air pattern into your living room. So help me God.

Stay tuned to the news.

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.
