Thank you, mdsimon2.
@amirm did you move your hosting service to Facebook? Edit: Because this thread reminds me of why I left Facebook:)

Lovely, isn't it ?
As you see, the noise from the signal is increased by the gain you are applying at the amp, so the lower the gain, the better....if I am understanding well, that's it.
DACnoise x 10^(AMPgain/20) = DACnoise at amplifier output=DACnao
Then (DACnao^2+AMPnoise^2)=Total noise
And if the total noise is in the mid-100 uV, there is no hissing.
Yupiiii.
