With these sort of specs you only need a passive preamp
Just use the built in attenuator as the volume control, and use an input switch box, like this

Or leave your attenuator full up and just get a $49 Schiit Sys which has two switchable inputs, you’ll be fine with your cd’s, and you’ll have enough volume with your phono preamp as well if it’s high enough gain.

Is there a reason I need a preamp other than the convenience of switching between the two?No your Bob Latino ST70 has an input impedance of 280kohm and sensitivity for full wattage output of just 1v in.

Would a ss preamp or passive preamp add to the sound? I presume any preamp would only degrade the quality and can’t make it better than it is.Yes any active preamp will add colouration to the sound.
