This depends on where the volume control is placed in the circuit and the S/N ratio of the components that are placed after the volume control. For example, if using an integrated tube amp (or separates) with a so-so or poor S/N ratio for the outputs (which are placed after the volume control in the circuit), turning down the volume knob does not reduce the power amp's S/N ratio. However, if the poor S/N ratio is due to the preamp circuitry that precedes the volume pot, then turning down the volume does reduce the S/N ratio along with the signal. Note there are some analog preamps that still have circuity placed after the volume control -- a buffer circuit, for example.
So, a healthy measure of "it depends" when it comes to the subject line. The good news is that most equipment is so quiet these days than it is generally a non-issue.
