Um, no. It's actually somewhat reminiscent of the SR007, except with more impactful bass slam, a more forward presentation, and less resolution. The HE-6 is the first planar I've liked since using Stax as my main rig.
My hunch is most typical headphone amps are incapable of properly driving the HE-6.
You can amp the HE-6 for as little as $225.
