whatever is the standard peak-to-peak voltage
for consumer audio (~ 2vpp?). Otherwise, we'll risk electrocution when they
invent 64 bit DACs :-)
The limiting factors are the output impedance of the converter,
(which is a thermal noise source, no matter how good the DAC
is) and the noise floor of the output opamps.
Since most opamps can deliver much more than 2 Vpp, and
pro levels are higher anyway, it makes sense to expand
the range at that end.
