You know, I really do not understand why the AE-1 seems to be the red-headed stepchild of HeadAmp's lineup. All of Justin's other amplifiers are respected and/or revered here at Head-Fi, but the poor AE-1 doesn't seem to get much love. Not to bash RSA's products AT ALL, but I stacked up my AE-1 against The Hornet and preferred it by far. It had more air, tighter bass, better soundstage, better materials/build quality, and was more versatile as a headphone amp that works equally well in both portable and home rig roles. Granted, neither amp was really burned-in at the time of my eval (I find the claim that "certain" solid state amps require 300+ hours to be, shall we say, beyond logic), but IMO the AE-1 rather handily came out on top as the superior product.
