I've had the ASL MG Head MK III (I like a lot of Divergent Technologies gear, but they could use a poet-in-residence to help with product names) for just about two months now, and absolutely love it with my Grado 325 golds. It is my first serious taste of the SET sound, and I find it quite magical. The sense of living air around the music, the resonant detail; wonderful. Before that, I had a perfectly competent MF X-Can; but for me, the ASL SET tubes with headphones is a match made in heaven....
