I'm pretty much there with most of my music (rig in sig). I do want something else for hard rock though, and I think I'm gonna get an Eximus S1 amp to go with my DP1, along with an HE6. Or I might get a Realiser instead since the cost is about the same. But for the here and now, my ZDSE/HD800 combo is my nirvana. :)
I like my HE-6 / First Watt F!J a heck of a lot..
