No, that is not the problem. Clipping the amps inputs would not be a
problem until you reach the maximum power capability of the amp, at
which point it doesn't matter by what means you got there.

The issue is that the source device's (SB's) outputs can only reach
some specified maximum voltage by design. Attempting to increase the
level digitally will simply clip the signal (horrible, hard clipping)
against that maximum voltage level.

The thing you're looking for is exactly the definition of a traditional
preamp. Now, a "digital preamp" could accomplish this just the same as
an "analog preamp", but a proper digital preamp would be capable of
significantly higher output voltages than a Squeezebox (or CD player,
or whatever).
