I have a four way headphone amp, and it it easy enough to daisy chain a
few together.
If you use most domestic power amps for your headphones, they use a
series resistor to cut the power down so you can't go deaf. Ss the
headphones are not a resistive load, this does some strange things to
the frequency response as well as wrecking the damping. Mind you, I'm
still waiting for a pair of headphones that sound the same to you as
they do to me.
Headphone amps start at a much lower power level, so the output
impedance can be lower, which gives a more level FR and better control
of transients.
