The gain setting slightly changes both the frequency response and transient response. Have a look at the Stereophile measurements. Also, the gain setting effects what point you use on the pot which relates to channel balance as well as how much conductive plastic the signal has to go through. I believe the change in resistance at that point also effects the interaction of the output impedance of the pot (or SA) and whatever follows it.
