Well, if not "obvious" then it is at least likely ... Noise introduced by the amplifier after its gain control is of course irrelevant here - it is whatever it is and nothing we do with the TP will change it. Similarly, noise introduced in the TP *before* the attenuators is fixed in relation to the signal and can't be affected by what we're doing here. On the other hand, noise introduced by the amplifier *before* its gain control will be amplified more if the input is lower: so introducing attenuation within the TP will make this worse. Similarly noise introduced in the TP after the attenuators, or in the connecting wire, will be more noticeable if you have a lower TP output. So, as you say, it depends on where the noise is being introduced: but there isn't any place that SNR will be improved by lowering the TP output level. That's not to say that the overall sound won't be better - its plausible that there are distortion effects within the amplifier which means that a "nicer" sound is produced at differing gain levels, but this is not the same as an SNR discussion. IMHO.
