I'm the very happy, monogamous owner of an Earmax Pro Silver Edition, also. I picked it up on the Headfi For-Sale forum last summer; it languished for quite a while on the forum before I worked up the nerve to get it. Shortly thereafter, I splurged on some great tubes (Telefunken 12AT7 from the 1960s, a pair of Amperex Orange Globes 7308s from the early seventies). After that, my lust for others amps evaporated. Check my profile for the headphones I use; the one I prefer the most is the AKG K701 (although I'm slowly beginning to really, really like the Grado RS-1s with the amp).
It's an amp that doesn't seem to get much press on the forums, but whenever it is mentioned, it's mentioned with very high praise , mostly by Those in the Know. That's part of the reason why I took the risk of buying it before hearing it. Call me superficial, but I also love its clean, funky look and small footprint.
I'm very close to pulling the trigger on a set of HD-600s, then getting a APureSound V3 cable for them. There are quite a few posts about the EMP + HD600 combo, but mostly from five, six years ago. Anyone care to post current impressions of that particular match-up?
