It gives me great pleasure to reveal a stunning new amplifier development. BEAR Labs, which is my company, has developed an entirely new distortion reduction methodology, which actually "deletes" distortion before it happens. Several years in engineering development and simulation have finally culminated in the first working engineering prototype. The results are stunning, exceeding expectations.
The comment from the team's lead engineer tells all: "...I have no idea how the h**l we are ever going to measure this thing, the only way I can tell it apart from a wire is that it has a different looking noise floor!..."
The principle behind the new amplifier module works something like this. It's been described as feedforwardback with feedbackforward WRT the inversion of the second order loop phase magnitudes.
In terms of hardware implementation the engineering team said that the scheme works because of the use of advanced, ultra high speed, leading-edge Gallium Arsenide microwave devices. This permits the supporting distortion reduction circuitry to in effect work to cancel the distortion before it happens, looking at it from the point of view of the signal amplifying devices! According to the engineering team one of the reasons that it took so long to build the actual physical prototype was because of the speed of the distortion reduction circuitry, as the team discovered that part of the flaw in traditional distortion cancelling circuits is the minute differences in time between one path and the other.
The key to controlling this critical problem came in the form of the Cancellation Reduction Adjustable Phase topology utilized in concert with the feedforwardback coupled with the feedbackforward design.
This is a quantum leap and order of magnitude development in amplifier design and implementation.
More information to come.

Unfortunately, it is not possible to build this circuit on a traditional PCB due to the propagation speeds involved.
I'll say more about the construction technology later today...

what a stroke of luck - i just won a big lottery and and have money to invest.
i'll have my people call your people so we can make this happen.

Bear,
This sounds like some previously hidden technology that the NSA has developed called the Merry-Go-Round circuit. You put something in at the beginning and it just keeps coming back around, the distortion is unmeasurable, a Mobious distortion reduction method where there is only one side to the ac distortion mechanism, only the A disappears but the C goes around and around. Hence zero distortion.

Can someone get a hold of SY and see if he can get an article up on Stereophile on this one? diyAudio's foremost subjectivist needs to jump on this opportunity!
Right, for being able to eliminate the limitations of space-time continuum, so that you know about the distortion, that will happen, before it happens, and correct it in advance 😀
Electrons have to overcome the light-speed barrier for making this possible 😱
Only works on the 1-st of April 😛
Well Bear I do need a post amplifier for my oscillator which is transparent to the osc's distortion and noise. When will there be more information.
any schematic available..??
Great time of year, today the sun was shining and my friend had birthday, he jokes a lot.

And, instead of saying: ..."The silence that follows Mozart is even Mozart", Sacha Guitry should have said: "The silence that precedes Van Halen is already Van Halen".

I think there should be a scientific study of why these things only work on April 1st? If we could just get them to work on April 2nd we could double the effect, think of that, a 100% increase over what we can do today! Why hasn't the government or private industry not studied this phenomena, or have they and are keeping it for future profit potential?
Have any of you actually tried to use a GaAsFET front end, even if ony for intellectual curiosity, or just to say you did it because you could? That 100 kHz 1/f noise corner could be a real *****. I don't suppose it's any crazier than using a 12AX7, in principle.
At least GaAs is (relatively) cheap these days. I rememeber $300 C-band low noise devices from back in the early days of "free" satellite TV. It's come down a bit since then.

I don't want to talk politic here, and don't know what happens in your country, but in mine, they already use-it: they have already spent in advance all the profits that could have been drawn from it.

Your correct as always Christophe, they already spent the money, before we even knew it existed! That most definitely is equivalent to correcting the distortion before it even happens. It's like it never happened.
Notice, Steven, that we are damn fast, ourselves. We vote for them before they have time to do their b...t
