Hi Dale,
    It's not probably a matter of personal taste as much as it is a circuit
design thing.  Impedance is the ruler in the audio signal chain world.  Not
to get too technical it goes something like this:
    Impedance is the AC resistance of a circuit.  Unfortunately this value
varies over frequency as well as pressure from the input voltage.  For
example, your speakers may be rated at 8 ohms.  This may be well and good as
an average, but in reality the impedance varies greatly depending on the
input voltage and resistance ---- and further varies in the output system
over each frequency.  To give a minimal example:  If a constant voltage was
input and swept upwards in frequency a variation in volume must occur in the
output (audio via speakers or via a signal jack).
    So my final suggestion is this:  Be careful and conservative in how you
pump each stage.  The dynamic interaction (read: unpredictable) can be a
blessing or a curse.
