So, is there agreement that a simple way to have vintage , or not so vintage, equipment have the same approx. sensitivity at the same position of the Volume control for different inputs, could do so with some passive resistor networks to reduce the input voltage? Maybe $0.20 worth of parts soldered at the RCA connector.

you said you can do the same thing with your 5 yr old onkyo. that's not vintage that's why we lock menu's.I like the idea but don't see that on the VLC Media Player software.
Are you talking about a menu on my receiver or on my PC?
Not obvious that I can lock either one.

I've seen receivers with an active buffer before the volume control, but this is rare. In most cases the volume pot trims the voltage to a safe level that avoids overload (including your Sansui, Andrew).
A lot of of newer equipment uses semiconductor switches to do the input selection instead of mechanical contacts. In these designs the front panel switches that you operate do not handle the input signals directly. There may also be an active buffer ahead of the switch in there too.
All of this is before the Volume control, so one could generate distortion by exceeding the design limit for these components.
Not sure where to look for some helpful specs on this?
I'd guess that these circuits came into common use by the mid 80's with the most popular consumer brands.
A little winter experimentation is called for................
