HP4 : Really good value, nice features

With this unit, you can send four individual cue mixes, unlike other similar boxes in this price range where you only can send one or two stereo mixes to the headphones. The headphone amps has enough power to work with both hi z and low z headphones and delivers a pretty good sound. Not the same detailed sound as in my Motu 1248 headphone amp, but good enough for cue mixes. There's enough info across the whole frequency spectrum for the musicians to get a feeling of what's going on. Build quality is pretty good, but lacks at little bit consistency; all the pots doesn't feel the same. But for the price they work more than ok. I've used it a lot for the last couple of years and have had no problems with it. In fact I will get one more unit because sometimes 4 headphone mixes aren't enough-
