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

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,

I honestly wonder if you're not ripping off somebody else's work and hocking it as your own.

 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.

There’s nothing to find out because you’re a liar, quite possibly a thief of intellectual property, and not producing something of terribly high regard. You have no reputation so great that your word alone is enough to make your silly claims believable. I know for a fact that your silly claims and meaningless explanations strike people as absurd and fictitious. People who know something realize real quick you don’t make any sort of sense. I’ll eat my shorts the day I see Stereophile review one of your jokes. JA would rip you and your gear apart. For crying out loud, Roger! What little you do say spec-wise isn’t even impressive. What the hell is "near zero" harmonic distortion? .005%? .0005%? 5Hz-50kHz +0/-3db? Am I supposed to be blown away by that? A 100wpc amp that weighs 35 pounds??? That’s gotta be class D to make that kind of power with such a flimsy weight. You either have a joke for a power supply or need no heatsinks. My bet is both. It’s probably got an SMPS and a pile of class D modules from somewhere. That’s probably why you can’t say anything that makes sense about the amplification circuit. You don’t even know what it is. I’ll also bet that these advances you speak of have nothing to do with distortion. You’re probably just finding better ways to manipulate and filter out the noise. And that Stereo Times review... Aside from the fact I’ve never even heard of it, I went and looked up his claims that your amp earned a Golden Ear award from TAS. No, it did not. Yet another liar! Anyone out there surprised??? BS and lies, Roger. Verbal smoke and mirrors intended to fool the layman. And THAT is what I REALLY don’t like. There’s no reason whatsoever to believe your claims, your products is highly suspect simply based on it’s appearance and weight, and you invent elaborate, mythical, nonsensical explanations to bolster claims you cannot substantiate in the slightest. SNAKE OIL. You’ve got nothing but snake oil.

So.......what's the next development in speakers?
