For sensor it makes no difference if you have high iso setting with low light and aperture wide open or bright sun with small aperture. Both cases sensor receives little light and noise contriutes significantly Amplification does not improve signal to noise ratio, because both are amplified with the same amount. Amplifier could even add additional noise Greetz Jos
