Modulation impact when amplifying a DSB signal?

In AM plate modulation, also screen or other AM modulation,

I seem to recall the concern that as it is amplified in latter
stages some of the power of that modulation is lost - thus
the desire for the highest-level modulation possible -
despite the bulk and cost of huge modulators.

Is the same true of DSB or is the modulation level not affected
in the same way by multiple stages of amplification following
the modulated stage?

I am thinking of this in terms of a QRP DSB exciter using low 
plate voltage (125v) versus having to manage modulation at a 
higher power stage.
