Not much at this moment as I haven't spent enough time with the HE-500 but regarding the amp - mine is able to deliver to them 1.6W of rated power per channel. At full power, they play absolutely clean. I could hear in another room via open window the music played on them during burn-in reflected from another building roughly 15m away. It was totally clean and well articulated. I am sure these headphones would play clean at several watts RMS. They are significantly less efficient (read: the volume setting on a low output impedance amp) than Beyerdynamic T1 or AKG K701. I prefer their presentation and rate their quality a bit higher than the HD800 or the T1 but so far, they can't touch the Grado PS1000 in terms of holography and sound texture. They are also (sic!) heavier than the Grado and clamp on the head considerably.
