HA4700 four channel headphone amp. Lots of control options like inserting separate channels for "more me" mixing, eight actual headphone outputs, clean sound, reliable, works perfect. I've had it for a few years and needed to trade in for an amp with separate monitor level controls. If you're on a budget, the place to take advantage of behringer gear is with your headphone amp.
