What are the sonic differences between various type of SMD resistors??

You said that the the feedback loop can't act upon the feedback resistor itself .If its value drifts away you're right, but that wouldn't be significant if the resistor's dissipation power is chosen well and again...

I don't understand this your statement. Don't you see a contradiction in your words?
You say something like: " Feedback loop cures a distortion of feedback resistors, but if they drift (distort) - then not".
Hm...

All the electric components inside the feedback loop bennefit of feedback correction, including the feedback resistor.

But how feedback resistors can benefit?
For example, with a feedback resistors noise - does feedback loop lower a noise of feedback resistors or not? (not).

if only one resistor of the feedback divider value would be drifting away, theoretically the distortion would vary with the new gain...that is why i said that you can apply the series identical resistor technique to match the drift in both sides of the feedback divider.

they were talking about the distortion not noise.The noise only reduces with the corespondent value for the closed loop gain ...

Why do you doubt that the resistors in the feedback loop can cause distortion. Or, that these distortions would be corrected?
