While EMM enjoys a very good reputation, there are other options out there as well. My Audio Synthesis DAX Discrete, placed on a slightly tweaked Machina Dynamica Promethean Base, matches the resolution of my analog system, and provides nearly as much enjoyment.
FWIW, the DAX Discrete is more popular in Europe than here in the US.
