Review: wow... - best budget 4 channel headphone amp for studio, jam rooms theatre etc, even though it's a 4 channel.. actually there is 12 headphone out, 2 monitor out and many inputs.. at this price i wasn't expecting that much quality but after testing even on full volume there is almost no distortion in the audio, reliable and sturdy, as it is black colour you can also hide them easily and make your desk tidy... thanks mackie for an affordable HA... love it.
