Planars don't have physical movement that needs to be dampened, but they still present an electrical load to the amp, which can affect frequency response.
Is this correct?
But the load across the frequency spectrum is flat with orthos...quite different from most regular dynamics:
The curve you see in the frequency response plot is due to the mechanical resonance of the dynamic driver. I do think that impedance matching is still reasonably important for orthos, an amp, headphone impedance mismatch will create a standing wave which in turn causes signal attenuation. I think the reason why you like the high impedance tap because orthos require a high voltage swing from the amplifier. Since V=iR, if R is big, i can be small to cause a big V.
