Dual distortion decreased noise?

[preciousmolina666]

ive read if you built dual preamp it minimized the boise. how about in TS/wampler opamp?

ive also read Sabrina managed the opposite with "boise - boise - boise"..

Apart from the spelling (and jokes about it), I think you need to make your question clearer if you want to get a useful answer from people here.

Do you mean that a person should use a dual op-amp chip?  Do you mean that a person should use two complete circuits?  I don't understand your question.

(No need to apologize for your English.)

Which part/item/device of the above could reduse "noise"..??

By halving a signal, amplify the two halves (equaly, I presume) and then adding them has nothing to do with noise reduction..

S/N ratio doesn't alter and the same stands for NFB noise rejection..

Or do I miss something else..??

All I can think of is that if you try to boost a signal too much in one stage, you introduce instability...trying to amplify too much at once = instability.   It is a better practice to 'sacrifice' some of the gain of one device and use two in order to increase the stability of a circuit.   Not doing this is more likely to cause oscillation rather than noise, however.

A well-designed and built input section with a modest gain increase to bring your signal above the noise floor before being introduced to the clipping section should be the best way to make your distortion as noise-free as possible.   This includes shielding input wire, short leads and so on.   But any high-gain circuit will also be amplifying ANY noise in the path, and there always is some, so this is relative....distortions do have hiss/noise by virtue of what they are.   

As far as I know, to create a nearly silent distortion, the easiest way to do this is to use a noise gate.
