Why? What will happen if I don't?

You'll get different levels on bass, mid and treble, which you'll have
to adjust via the active crossover.

Each amplifier also has its own volume control (the Cyruses are integrated
amps, the valve has an independent vol on each channel).

If the issue is primarily one of disparate gain, then I don't think that's
an issue. The sensitivities of the amps for full power are all around
200-300mV, and the DAC, as you may be aware, puts out 2V (pk-pk). As it is,
turning the preamp much over half-way causes the limiter LEDs in the
crossover to flicker (the limiter is adjustable, and is set to +6dB).
